When elements react together to form compounds their atoms join other atoms using chemical bonds. There are two types of bonds, ionic and covalent bonds. Ionic bonds are formed through an electrostatic attraction. Covalent bonds are formed by electrons shared by atoms.

This is an image of tide. Tide is a type of washing soda found in common homes. It is used for laundry and washing clothes. It is made out of Na2CO3. Which is colposed of sodium,carbon and oxygen.
This image is toothpaste. Toothpaste is used for cleaning your teeth. It is made out of MFP. MFP is monofluorophosphate.

Ionic and Covelant Bonds

DANIELA ZUNIGA RAMIREZ
​Every combination of atoms is a molecule. Compounds are formed together when two different pure elements combine together. Now a compound is a molecule  made of atoms from different elements. All Compounds are molecules and yet not all molecules are are compounds.An example is that (H2) is not a compound because, its only one element while H2O is a compound because it involves two elements Hydrogen and Oxygen.
      There are two types bonds well, let me rephrase that there are two most common bonds and they are Ionic and covalent bonds. Ionic bonds are when the atoms transfer electrons to each other. While on the other hand Covalent bonds involve sharing a pair of valence electrons by two atoms.

Ionic Bonds In My House:
 
Marble floor

Chemical compunds

Compounds are formed when an element of an Atom join with another element of an atom to form a substance. There are 2 types of Chemical bonds : Ionic Bonds and Covalent Bonds and they are both very different, Ionic bonds connects with Metals and Non-Metals and the reason why they connect is because they end up getting electrical charge. They form when two elements with the opposite charge join together. Covalent bonds form when electrons are lost or gained to achieve the octet resulting in the formation of Ions  

here is a picture of vinegar, vinegar is covalent bond and that's because vinegar has magnesium, phosphorous, chlorine, sodium, sulfur, potassium, calcium, copper, iron, silicon and fluorine. The formula for vinegar is C2H4O2.

This a picture of Backing soda is made out of sodium which makes it an ionic compound . The formula for Baking Soda is NaHCO3


This is sugar, sugar is a covalent bond since C12H22O11

Ionic and Covalent Compounds

A compound is formed from atoms of different chemical elements. The different elements are then joined by chemical bonds. There are two types of chemical bonds, covalent and ionic bonds. The difference between a covalent bond and an ionic bond is that covalent bonds form when valence electrons are shared between atom, where as an ionic bond is formed when electrons are transferred between atoms.

Examples of Ionic Compounds: 


Soap is an ionic compound because it is made out of sodium hydroxide. The chemical formula for soap is CH3COONa. 


Baking Soda is an ionic compound because, ionic bonds are formed with metals and nonmetals. Baking soda has sodium as its metal and hydrogen as its nonmetal. The chemical formula for baking soda is NaHCO3. 

Examples of Covalent Compounds: 


Sugar is a covalent compound because, it is made up of nonmetals. It is made out of carbon, hydrogen, and oxygen. The chemical formula for sugar is C12H22O11. 


Oil is a covalent compound because, it is made up of nonmetals. It is made of hydrogen and carbon. The chemical formula for oil is C22H42O2.
-Kaitlyn Goff 


Covalent and Ionic Bonds

Compounds are formed when two or more elements have formed and bonded. There is two different bonds. Those are the ionic bonds and the covalent bonds. The differences between the ionic and covalent bonds are that the ionic bonds are "the complete transfer between valence electrons." It's also where the metals lose electrons to become positively charged. And where the nonmetals gain those electrons to become negatively charged. And that's where those two elements have formed to make a compound. Ionic compounds are also where negative and positive charges are attracted to each other. That's why electron valences are being traded off so that one can become positively charged and the other can become negatively charged and the both of them can be attracted to each other. Covalent bonds are the chemical share of electron pairs between atoms.

Covalent Bonds: 

-Oil: Chemical Formula- C36H74
we use oil in everyday life as in having to cook fries:)) or having to fry food so we can eat it so we can stay alive. 

-Sugar: Chemical Formula- C6H12O6
we use sugar in multiple things, including cake, tea or coffee, and anything that is being cooked or stirred with sugar:)

Ionic Bonds:

-Soap: Chemical Formula- C35H17COONa
we (hopefully) use soap every day after using the bathroom, before and after eating, and while taking a bath. 

-Toothpaste: Chemical Formula- Na2PO3F
we use toothpaste (hopefully) twice a day, everyday to keep out teeth clean and to keep people around us alive:))

Fwd: Ionic Bonds & Covalent Bonds

Compounds are substances that are made of two or more different elements. These compounds are formed by the occurrence chemical reactions. When elements react together to form chemical compounds, their atoms are combining together in a process called chemical bonding. Bonds help determine the properties the newly formed chemical compound will possess. 

There are two common types of chemical bonds; ionic bonds and covalent bonds. Ionic bonds are formed when containing particles that are opposite charges of each other that attract each other. Each ion attracts nearby ions with a charge opposite to theirs. Atoms can be gained and or lost in ionic bonding.This type of bonding makes for a stable and strong compound. Ionic bonds are formed typically between a metal and a nonmetal. Whereas, covalent bonds are formed by the sharing of electrons between a pair of atoms. Covalent bonds appear typically between a nonmetal and, well, a nonmetal. And the atoms in this bond neither gain or lose an electron, since they share- this mean there are no ions. 

Examples of Ionic Bonds In Everyday Life

                 ​​​

Here is sodium fluoride, it's chemical formula is NaF. NaF is an ionic compound, this is because sodium (Na) is an alkali metal whilst Fluorine (F) is a halogen- a nonmetal type of element, and it's a known fact that ionic bonding is between a metal and a nonmetal. Sodium fluoride is used in toothpastes (as seen above) for teeth strengthening purposes, added into drinking water, used a preservative in adhesives and glues, and pesticides. 

                                                        ​                                                            
Here we have baby powder that contains a chemical compound that is bonded ionically, benzethonium chloride, commonly known as; hyamine. The chemical formula for this substance is  C27H42ClNO2. Benzethonium chloride is an ionic compound because at the end of it's name it contains the suffix -ide, which is usually found in the name of ionic compounds. It is used to kill bacteria, in toiletries and cosmetics. 

Examples of Covalent Bonds In Everyday Life

                                                                        
Here we have some disinfecting bathroom cleaner that contains ammonia. The chemical formula for this substance is NH3.  It is a covalent compound because it contains Nitrogen (N) and Hydrogen (H), both being nonmetal elements. It is a known fact that covalent bonding is between two nonmetal elements. Ammonia is commonly used in house cleaning products such as the disinfectant above and in food and fertilizers. 
     
​                                                                        
This is pure epsom salt, scientifically known as hydrated magnesium sulfate. The chemical formula for it is MgSO4 + 7H2O. It is both an ionic and covalent compound. But since i've placed this underneath covalent bonds, i'll explain the covalent compound part of it. The 7H2O is the covalent part, containing hydrogen (H) and oxygen (O) both nonmetal elements. And as for the ionic component of the compound it's the MgSO4, it contains; magnesium (Mg) and sulfur (S) and oxygen (O)- magnesium is a metal while the other two are nonmetals, this combination results in an ionic compound as ionic compound is the attraction of a nonmetal and metal. Hydrated magnesium sulfate is used as a variety of therapeutic solutions (as said above on the packaging).

Ionic and Covalent in the house! - Ryan

          What are Ionic and Covalent bonds? Ionic bonds: If one atom gains and the other loses the electron. ( metal to a nonmetal) The outcome of the transfer of electrons between two not similar atoms. Covalent bonds:  If atoms share the electrons. ( nonmetals or metalloids ) 
Some compounds that I found in my house that are Ionic are: NaOH - sodium hydroxide - found in some surface cleaners as well as oven and drain cleaners - Detergent (because Na is a metal and O and H are nonmetals); CaCO3 - calcium carbonate - found in calcium supplements - chalk, limestone, marble, and calcite, (because Ca is a metal. and C and O are nonmetals)

Some compounds that I found in my house that are covalent are: CH3COOH) - vinegar - glacial acetic acid- food, cooking - (because C is a nonmetal H is a nonmetal and O is a nonmetal, similar bonding); C4H10 - Butane, is found in cigarette lighters (because C is a nonmetal, H is a nonmetal, and O is a nonmetal)

Ionic & Covalent Bonds

Compounds are formed when elements of an atom join with another elements atom to form another substance, this happens using chemical bonds, for example the reaction between sodium and chlorine forms the compound sodium chloride. There are two main types of bonds, Ionic bond and Covalent bond

Ionic Bonds: They are formed in which one or more electrons from an atom, are removed and attached to another atom. This chemical bond happens when a positive and a negative ion are being generated

Covalent Bonds: It is a chemical bond that involves sharing of a pair of valence electrons by two atoms. If there is a covalent bond between two atoms, neither atom lose or share an electron, so no ions are formed

Examples of Ionic Bonds

Toothpaste


A toothpaste is used to clean your teeth everyday and makes your teeth smell good and fresh. Toothpaste has sodium fluoride, which is a chemical compound. The chemical formula for a toothpaste is NaF (sodium fluoride)

Baking Soda


Baking soda is used for cleaning and cooking also. Baking soda has  Sodium Bicarbonate and the formula for baking soda is NaHCO3 ( Soduim, hydrogen, carbon, and oxygen)

Examples of Covalent Bonds
Vinegar


Vinegar is used in cooking, and cleaning. It is made up of acetic acid and water, and is also known as dilute acetic acid. The chemical formula for vinegar is CH3COOH.

Sugar




Sugar is used for sweetening certain things for example coffee. The chemical compound in sugar is carbon, hydrogen and oxygen. The chemical formula for sugar is C12H22O11.

Chemical Compounds

Compounds are formed when an element's atom joins with another element's atoms to produce another substance suing chemical bonds. There are two types of bonds: Ionic bonds and covalent bonds. Ionic bonds are when two elements with opposite charges join together. A covalent bond is the sharing of electron pairs between atoms. 

Example of ionic:

Here is a picture of baking soda, vinegar and sugar. Baking soda is a  ionic bond. Its formula is  NaCO3  its ionic because it is made up of sodium, a metal, and carbon, a nonmetal.. Vinegar has the formula of C2H4O2. It is a covalent bond since Carbon, Hydrogen and Oxygen are nonmetal. And sugar is covalent too. Its formula is C12H22O11. Carbon, Hydrogen and oxygen are all non mentals.


-Yasmeen Khazindar

Compounds

Compounds are formed from basic substances by chemical reaction. It is the reaction between atoms from the same element or between atoms of different elements that leads to the formation of compounds.

The distinction between ionic compounds and covalent compounds is In ionic bond the atoms are bound together by the fascination between inverse charged particles. For example, sodium and chloride form an ionic bond, to make NaCl, or table salt(Na is alkali metal and Cl is a halogen nonmetal. In a covalent bond, the molecules are bound by shared electrons. On the off chance that the electron is shared just as between the iotas framing a covalent bond, then the bond is said to be nonpolar. For example, the atoms in water, H2O, are held together by polar covalent bonds.

Examples of covalent compounds:
 
Glass is a covalent compound (SiO2) because the primary element of glass is silicon dioxide, SiO2. It forms a network solid, so the bonds are covalent. Glass is used to to make bottles, jars, cups,etc. 

Sugar is covalent compound (C12H22O11) because you can see that sugar is produced using nonmetals component and we realizes that covalent bond is structures between nonmetals. We use sugar in our everyday life in food.

Examples of ionic compounds:
 
Soap is an ionic compound (C₁₇H₃₅COONa) since it is made out of sodium hydroxide. We use soap in our everyday life to wash our hands. 


Baking Soda is an ionic compound ( NaHCO3) Since sodium is greatly receptive it will just show up as a cation. The bicarbonate particle is anionic. joined they are a salt otherwise known as ionic compound.

Chemical Compounds

Compounds are formed when two different pure elements combine together. Every combination of atoms is a molecule.A compound is a molecule made of atoms from different elements. All compounds are molecules but not all molecules are compounds. An example of this scenario would be that (H2) is not a compound because it is only one element while H2O is a compound because it is involves two elements Hydrogen and Oxygen.

          The two types of most common bonds are ionic and compound bonds. Covalent bonds involve the sharing of a pair of valence electrons by two atoms. On the other hand, Ionic bonds are when the atoms transfer electrons to each other.

Ionic Bonds found at home:


Toothpaste which is used to brush your teeth. The chemical compound in toothpaste is sodium fluoride. The chemical formula for toothpaste is NaF.  

Marble is used for the floor, counter tops and household items. The chemical compound in marble is calcium, carbon and oxygen. The chemical formula is CaCO3.


Covalent Bonds found at home

:

Sugar which is used for sweetening,. The chemical compound in sugar is  carbon, hydrogen and oxygen. The chemical formula for sugar is C12H22O11.

Chemical Compounds

 How are compounds formed? Compounds are formed when chemical reaction occurs. This chemical reaction causes the atoms of the different elements to bond meaning they are pulled together by a force.

 

 

There are two types of bonds, covalent and ionic bond. Covalent bonding occurs when pairs of electrons are shared by atoms. These atoms will then covalently bond with other atoms to gain more stability by collecting more electrons to have a full outer or valence shell. Ionic bond on the other hand is when a complete transfer of valence electron(s) between atoms occurs. It is a type of chemical bond that works with two oppositely charged ions. 


Two Ionic Compounds:

​​​

​Baking soda/ Sodium bicarbonate: Is consist of the compound NaHCO3. When sodium and the bicarbonate ion mixes they form salt also known as ionic compound


​Surface cleaner: is made up of sodium hydroxide or NaOH, these are oppositely charged ions.


Two Covalent Compounds:



​Sugar/ sucrose: Sugar, glucose is just a covalently bonded chain C6H12O6. A sugar crystal is just millions of these single glucose chains stuck together with weak intermolecular bonds. When you dissolve the sugar in the water those light weight bonds break and the sugar dissolves down to the single glucose chains but does not break into ions, so it is not an ionic solution. Sugar can be useid as a sweetener for food or drinks.

"New substances are formed by chemical reactions. When elements react together to form compounds their atoms join to other atoms using chemical bonds. For example, iron and sulfur react together to form a compound called iron sulfide."

I found this link and i think it shows a lot of good examples

The two opposite Ions attract  and form the ionic bond. 

Covalent bonding  is a form of chemical bonding 
Between two non metallic atoms.

ionic=Most cleaning products have ionic compounds like arial. jeff and clorax. they are used for cleaning and the chemical formula for clorax is 8% sodium hypochlorite and 0.01–0.05% sodium hydroxide

Covalent bonds= vinegar continues acetic acid and it has a chemical formula which is CH3COOH it has a covalent bond.

Ionic and Covalent Bonds and Compunds

​Compounds are formed by chemical reactions. When elements react together to form compounds, their atoms join together with other atoms using chemical bonds. For example, iron and sulfur react together to form a compound called iron sulfide. There are two types of bonds: ionic bonds and covalent bonds. An ionic bond is a bond that is formed by atoms losing or gaining electrons (ions). An ionic bond involves a metal and nonmetal ion. A covalent bond is a bond that is formed when atoms share electron pairs (these electron pairs are also called bonding pairs). There are two types of compounds: ionic compounds and covalent compounds. Ionic compounds are formed when ions are held together in a structure by ionic bonding. Covalent compounds are formed when two or more nonmetal atoms bond by sharing electrons (covalent bonding).


One example of an ionic compound is baking soda (NaHCO3) (also known as sodium bicarbonate). It is an ionic compound because ionic bonds are formed with metal and nonmetal atoms. Sodium (Na) is a alkali metal, Hydrogen (H) is a nonmetal (does not belong to any group), Oxygen (O) is a Chalcogen nonmetal, and Carbon (C) is a also a nonmetal (in group 14 but that group doesn't have a group name). Another example of an ionic compound is marble (CaCO3) (also known as calcium carbonate). It is also an ionic compound since its ionic bonds are formed with atoms of a metal and a nonmetal. Calcium (Ca) is a alkaline Earth metal, Carbon (C) is a nonmetal, and Oxygen (O) is a Chalcogen nonmetal.

One example of a covalent compound is sugar (C12H22O11) (also known as sucrose). It is a covalent compound because covalent bonds are formed with only nonmetal atoms. Carbon (C) is a nonmetal, Hydrogen (H) is a nonmetal, and Oxygen (O) is a Chalcogen nonmetal. Another example of a covalent compound is vinegar (C2H4O2) (also known as acetic acid,  or ethanoic acid). Carbon (C) is a nonmetal, Hydrogen (H) is a nonmetal, and Oxygen (O) is a Chalcogen nonmetal.


As you can see, there are ionic and covalent compounds all around us and we use them in our everyday lives, and that the same elements can form different compounds (sugar and vinegar are both different substances but they are both made out of carbon, hydrogen, and oxygen).
