Nitrogen does not lose or gain electrons. It is a diatomic molecule (N2) and is a molecular compound which has covalent bonding. In other words, the molecule has a triple bond, in which 6 electrons are shared, three for each atom.
Elements in the same family, or group will contain the same number of valence electrons and have many similar characteristics.
Oxidation number
The Halogen family.All but one of the halogens are nonmetals, and all share similar properties. A halogen atom has 7 valence electrons and typically gains or shares one electron when it reacts.Hope this helped.
In the ground state, it has 82 electrons. It usually only shares two of those electrons into an ionic bond.
In Chemistry, the family number tells you how many electrons the element gives, gains, or shares. It also tells you how many valance electrons you have. In addition and subtraction, number families include two lesser numbers and one greatest number (also called the smaller and larger numbers) such as 4+3=7 and 7-4=3
