Step-by-step explanation
Given, n = 5, ml = + 2
For n = 5, possible value of l = 0, 1, 2, 3, 4
For l = 0, ml = 0
l = 1, ml = 1, 0, 1
l = 2, ml = 2, 1, 0, 1, 2
l = 3, ml = 3, 2, 1, 0, 1, 2, 3
l = 4, ml = 4, 3, 2, 1, 0, 1, 2, 3, 4
Possible value of ml for a given value of l
= 0, 1, 2, 3 ..... l
So, number of orbitals having n = 5 and ml = 2 are 3.
