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

Options

(a) 14
(b) 16
(c) 10
(d) 12

Correct Answer:

14

Explanation:

n = main energy level
/ = subshell
If n = 4 and / = 3, the subshell is 4f. In f subshell, there are 7 orbitals and each orbital can accommodate a maximum of two electrons, so, maximum no. of electrons in 4f subshell = 7 x 2 = 14.
