Diatomic molecular nitrogen (N2) is a relatively inert gas that makes up about 80% of the air we breathe.However,the chemical element nitrogen (N),as a single atom,can be reactive and have ionization levels (referred to as valence states) from plus one to plus five.Thus nitrogen can form several different oxides.
