Covalent Bonds

Ionic bonds form between two or more oppositly charged ions.Metals form cations(+)non-metals form anions(-)

Here is a covalent bond, as you can see the hydrogen and carbon atoms are sharing thier valence electrons to make both of them stable.This bond would be written as tetrahydrogen monocarbide.

The main difference between covalent bonds and ionic bonds is that when an ionic bond forms, the two or more atoms that made it do not merge their electrons like that of a covalent bond. Only one atom recieves all the valence electrons and the other loses them. They do not share to become stable.

Covalent bonds form when two or more non-metals share electrons.

Ionic bonds form between two or more oppositly charged ions.Metals form cations(+)non-metals form anions(-)

Ionic Example

Covalent Example

Sodium gives Chlorine its only valence elctron, so its outer most energy level will be empty. This is allowing Chlorines outer most energy level to be full making Chlorine have a negative charge and Sodium have a positive charge. This would make both of them stable. This would now becom Sodium Chloride.
