WHAT IS A NITROGEN OXIDE? 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.United States Office of Air Quality EPA 456/F-99-006R WHAT IS A NITROGEN OXIDE?

chemical bonding Definition and Examples Britannica

Chemical bonding,any of the interactions that account for the association of atoms into molecules,ions,crystals,and other stable species that make up the familiar substances of the everyday world.When atoms approach one another,their nuclei and electrons interact and tend to distribute themselves in space in such a way that the total energy is lower than it would be in any alternative
