Question

Which of the following statements about the 5f subshell is true?

A. The principal quantum number is 5, the orbital angular momentum quantum number is 3 and the maximum number of electrons in this subshell is 14.

B. The principal quantum number is 5, the orbital angular momentum quantum number is 3 and the maximum number of electrons in this subshell is 20.

C. The principal quantum number is 5, the orbital angular momentum quantum number is 3 and the maximum number of electrons in this subshell is 10.

D. The principal quantum number is 5, the orbital angular momentum quantum number is 2 and the maximum number of electrons in this subshell is 10.

E. The principal quantum number is 5, the orbital angular momentum quantum number is 4 and the maximum number of electrons in this subshell is 14.

Explanation / Answer

principal quantum number is number in front. This is 5
orbital angular momentum quantum number for f is 3
that is l=3
for given l, number of electrons = 2*(2*l+1)
= 2*(2*3+1)
= 14

This matched option A
