What is the atomic number of the element, having maximum number of unpaired 2p electrons? To which group does it belong?

Text Solution

Verified by Experts

A p orbital can accommodate maximum of 3 unpaired electrons. So the electronic configuration is `1s^(2)2s^(2)2p^(3)`. The atomic number of element is 7 and the element is nitrogen. It belongs to V th group.
