IS n=2, l=1, ml=0, ms=1/2 POSSIBLE GIVE REASON

Expert Answer
- The three quantum numbers (n, l, and m) that describe an orbital are integers: 0, 1, 2, 3, and so on.
- The principal quantum number (n) cannot be zero. The allowed values of n are therefore 1, 2, 3, 4, and so on.
- The angular quantum number (l) can be any integer between 0 and n - 1. If n = 3, for example, l can be either 0, 1, or 2.
- The magnetic quantum number (m) can be any integer between -l and +l. If l = 2, m can be either -2, -1, 0, +1, or +2.
As per above rules,
when n=2, l= 0, 1, ml=-1, 0, +1 and ms = +1/2 or -1/2
Hence, n= 2, l = 1, ml= 0 and ms = +1/2 is allowed or possible combination.
