Answer to Question #332001 in General Chemistry for Bibi andak

Question

Can an e be described by the following set of quantum numbers? If not indicate which of the quantum numbers has a value that is not valid: n=2, £=1, ml= -1, Ms=+½

Answer 1

The allowed values of principal quantum number (n) are 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.

Spin quantum number (s) can be either +1/2 or -1/2 to distinguish between the two electrons in an orbital.

Therefore, an electron can be described by the following set of quantum numbers.
