How many unpaired electron(s) are there in the nitrogen sub-levels?
-
3
- 2
- 1
- none
The correct answer is: A
Explanation
Nitrogen has 7 electrons in all.
Its electronic configuration is = \(1s^22s^22p^3\)
So, it has three unpaired electrons in its p-orbitals.
Note that the p orbital can accommodate a maximum of 6 electrons
