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.
