Maximum covalency of an element of atomic number 7 is
The electronic configuration of an element of atomic number 7, is 1s 2 2s 2 2p x 1, 2p y 1 2p z 1 .The valence shell is second principal shell which has only four orbitals and the element can form maximum of four covalent bonds. Thus, the covalency is 4.
Hope this helps you.
