Which electronic configuration for oxygen is correct according to Hund's rule of multiplicity.

A

`1 s^2, 2 s^2 2 p^(2)._(x) 2 p^(1)._(y) 2 p^(1)._(z)`

B

`1 s^2, 2 s^2 p^(2)._(x) 2p^(2)._(y) 2 p^(0)._(z)`

C

`1s^2, 2 s^(2) 2p^(3)._(x) 3 p^(1)._(y) 2 p^(0) ._(z)`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
(a) Hund's rule states that pairing of electron in the orbitals of a subshell (orbitals of equal energy) status when each of them us singly filled.
