In which of the following, energy of 2s orbital is minimum

A

K

B

Li

C

Na

D

H

Text Solution

Verified by Experts

The correct Answer is:
A
Energy of 2s orbital `prop (1)/((Z_("eff"))^(2))," "Z_("eff"):K=Na gt Li gt H &Z:K gt Na`
hence the force of attraction of the K nuclei at 2s electrons will be stronger than that of Na nuclei.
