Bonds

Why do chemical bonds form?

• so the number of protons equals the number of electrons

• to fill the outermost electron level

• so an atom can become unstable

Nitrogen is a diatomic element which means in nature, it is found in two's. (N₂) Nitrogen shares three pairs of electrons to make sure each atom completes the octet rule. This creates a...
