Question
An atomic orbital has n = 3. What are the possible values of l and ml?
Solution
n = 3 (Given)
For a given value of n, l can have values from 0 to (n – 1).
∴ For n = 3
l = 0, 1, 2
For a given value of l, ml can have (2l + 1) values.
For l = 0, m = 0
l = 1, m = – 1, 0, 1
l = 2, m = – 2, – 1, 0, 1, 2
∴ For n = 3
l = 0, 1, 2
m0 = 0
m1 = – 1, 0, 1
m2 = – 2, – 1, 0, 1, 2
