Expert Answer:

Covalency is the number of covalent bonds that a particular atom can make with other atoms in forming a molecule.
The maximum covalency of nitrogen is 4 because it can donate the lone pair of electron to a lewis acid and three bonds are already  attached to it and oxygen donate two lone pair and make two bonds with other elements that make the covalency of O2 is 4,
