Maximum number of electrons in a subshell with l=3 and n=4 is

A

14

B

16

C

10

D

12

Text Solution

Verified by Experts

The correct Answer is:
A
`n = 4, l=3 rArr 4f` subshells
Since maximum no. of electrons in a subshell `=2(2l+1)`
So, total no. of electrons in 4f subshell `=2(2xx3+1)=14` electrons.
