Question

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

• A. 14
• B. 16
• C. 10
• D. 12

Answer 1

The correct option is A

14

First take a look at values of n and l.

n = 4

l = 3

Therefore possible orientions = 2l + 1= 2(3) + 1 = 7

Number of orbitals = 7

$\therefore$ Maximum number of electrons in one orbital = 2

$\Rightarrow$ Maximum number of electrons $=7\times 2=14$
