Question

Which of the following has non – spherical shell of electron?

• A. He
• B. B
• C. Be
• D. Li

Answer 1

The correct option is B

B

The electronic configuration of the given atoms are as

He $\to 1s^2$

B $\to 1s^{2}2s^{2}2p^1$

Be $\to 1s^{2}2s^2$

Li $\to 1s^{2}2s^1$

Among these atoms, only B has p sub shell which is a non spherical shell
