Expert Solution
Step 1

Introduction - 

Valence Electrons
 outermost electrons - the "s" and "p" electrons in the last energy level
electrons that form bonds
Magic Number EIGHT! Very happy!
 most elements either:
~ give electrons (+)
or
~ gain electrons (-)

Valence electrons- the outer most electrons on the Bohr model. 

Can participate in a chemical bond.

Nitrogen have 5 valance electron
