Question

In which pairs do both species have the same number of unpaired electrons in p orbitals?

1. O and Cl⁺
2. F⁺ and Ga⁻
3. N and Kr³⁺

Please help me in this question.

Answer 1

Answer:

1. O and Cl⁺ is the answer

Answer 2

O and $Cl^+$ have the same number of unpaired electrons in p orbital.

Option (1).

Explanation:

The O has the  electronic configuration

$1s^2, 2s^2,2p^4.$

Therefore the number of unpaired electrons in p orbital are 2.

When we look at Cl we see that its electronic configuration is as below

$1s^2, 2s^2, 2p^6, 3s^2, 3p^5.$

But we are given $Cl^+$, Therefore its configuration is given by

$1s^2, 2s^2, 2p^6, 3s^2, 3p^4.$

Hence the number of unpaired electrons in p orbital of $Cl^+$ is 2 which is the same as the number of unpaired electrons in p orbital of O.
