(d) Covalency of Nitrogen
A nitrogen atom has 5 valence electrons, so it can share its 3 electrons with three electrons of another atom to attain the 8-electron inert gas electron configuration. Since one nitrogen atom shares 3 electrons to achieve the nearest inert gas electronic configuration, therefore,the covalency (or just valency) of nitrogen is 3. For example, in the formation of a nitrogen molecule, , each nitrogen atom shares its 3 electrons with the other atom, so the valency of nitrogen in the molecule is 3.
