What set of quantum numbers n, 1,m,ms is invalid

Answer 1

The valid quantum number sets are that obey the following rules:

- n is a positive integer greater than or equal to 1
- 1 is an integer such that 1 ≤ l ≤ n − 1
- m is an integer such that −l ≤ m ≤ l
- ms is either +½ or −½

Therefore, an invalid set of quantum numbers could be, for example:

n = -1
l = 0
m = 1
ms = +½

This set violates the first rule, as n should be a positive integer greater than or equal to 1.
