What is the maximum number of electrons in an atom that can have the following quantum numbers
N = 3 $~~$l = 2
A) 18
B) 10
C) 5
D) 2
E) 1

Question

Quizplus · Accepted Answer

The maximum number of electrons for a given set of quantum numbers is given by the formula 2(2l+1). 
Substituting N=3, l=2, we get 2(2(2)+1) = 10, which is the maximum number of electrons that can have these quantum numbers. 
Therefore, the best choice is B, which gives the correct answer.
