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

A

1s2,2s22px22py12pz11s^{2},2s^{2}2p_{x}^{2}2p_{y}^{1}2p_{z}^{1}

B

1s2,2s22px22py22pz01s^{2},2s^{2}2p_{x}^{2}2p_{y}^{2}2p_{z}^{0}

C

1s2,2s22px32py12pz01s^{2},2s^{2}2p_{x}^{3}2p_{y}^{1}2p_{z}^{0}

D

None of these

Answer

1s2,2s22px22py12pz11s^{2},2s^{2}2p_{x}^{2}2p_{y}^{1}2p_{z}^{1}

Explanation

Solution

Hund’s rule states that pairing of electrons in the orbitals of a subshell (orbitals of equal energy) starts when each of them is singly filled.
