Answer 2

Electron configuration of oxygen is 2,6.

An oxygen atom requires two electrons to achieve octet configuration. Thus in an oxygen molecule, two oxygen atoms share two electrons from each of the atoms to attain an octet configuration. Hence two electron pairs are shared between two oxygen atoms forming two covalent bonds. Hence oxygen is also called a divalent compound.

Electronic configuration of nitrogen is 2,5.

A nitrogen atom requires three electrons to achieve octet configuration. Thus in a nitrogen molecule, two nitrogen atoms share three electrons from each of the atoms to attains octet configuration. Hence, three electron pairs are shared between two nitrogen atoms forming three covalent bonds. Hence, nitrogen is also called a trivalent compound.
