Calculate the number of unpaired electrons in N-atom.

Text Solution

Verified by Experts

Electronic configuration of N(atomic no.=7): `1s^(2)2s^(2)2p^(3)` According to Hund's rule, the 3 electrons in the 2p-subshell occupy the three p-orbitals `(p_(x),p_(y)p_(z))` singly.

Hence, the no. of unpaired electrons present in N=3.
