What are three sets of quantum numbers for each orbital where n equals 4 and L equals 3

Question

Quantum numbers unit finding quantum numbers for each orbital where n=4 and (l)=3 I'm not understanding anything in this subject

Answer 1

n = principal quantum number = 4 [given]

 

l = orbital quantum number

l = 0, 1, 2, ... , n - 1

n = 4 ⇒ l = 0, 1, 2, 3

 

m = orbital magnetic quantum number

m = -l, -l + 1, ... , 0, 1, 2, ... , l - 1, l

There are 2l + 1 possible values of m for each l.  For l = 3, m = -3, -2, -1, 0, 1 , 2, 3
