Ionic and Covelant Bonds
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:

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.

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.

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).
