# Problem: Which set of quantum numbers (principal, angular and magnetic) are  not valid?Set (1) 4, 2, -3Set (2) 3, 2, -2Set (3) 2, 2, +1a. Sets (1) and (2)b. Sets (2) and (3)c. Sets (1) and (3)d. all three setse. only one or none of these sets.

###### FREE Expert Solution

Establish the first 3 quantum numbers and determine which set of values are not valid

The first three quantum numbers are:

principal quantum number (n) energy level in orbitals and its value could be any positive integer starting from 1 to infinity

angular momentum quantum number (→ (l) has to be at least 1 less than n,range of values from 0 up to (n-1)

magnetic quantum number (m)→ range of values from - to +.
