Answer to Question #138369 in General Chemistry for Emilie Hrabal

Question

What is the maximum number of electrons that can have the following set of quantum numbers? n = 2, ℓ = 1, mℓ = 1.

Answer 1

This value of "n" can have the following values for the orbital angular momentum quantum number "l": l=0,1,

These values of "l" can have the following values of the magnetic quantum number "ml":

l=0, ml=0

l=1, ml=−1

l=1, ml=0

l=1, ml=1

The last set is the one given in this question, this corresponds to a single atomic orbital in the "2p" subshell. A single atomic orbital can only hold two electrons because the spin quantum number "ms" for an electron only has allowed values of +1/2 and -1/2.
