Which of the following orbitals has maximum enegry?

A

`2s` orbitals of `Li`

B

`2s`orbital of `H`

C

`2s` orbital of `Na`

D

All have the same enegry

Text Solution

Verified by Experts

The correct Answer is:
B
Energies of the orbitals in the same subshell decrease with increase in the atomic number `(Z)`, thus, the enegry of the `2s`orbital of `H` atom is gerater than that of the `2s` orbital of `Li` and that of `Li` is greater than that of `Na`, and so on, that is, `E_(2s)(H) gt E_(2s)(Li) gt E_(2s)(Na) gt...`
