Which of the following is a possible set of quantum numbers for an electron (n, l, m0, ms)? (1, 1, 0, +1/2) (2, 1, 2, +1/2) (3, 2, 0, -1/2) (3, -2, 1, -1/2)

OpenStudy (cuanchi):

I was helping you yesterday with the same question, and I didn't get you back

OpenStudy (anonymous):

I'm sorry, I got busy but I reallyy need to figure it out now!

OpenStudy (cuanchi):

Rules Governing the Allowed Combinations of Quantum Numbers 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.

OpenStudy (cuanchi):

What is the "n" value of the electron for the first answer?

OpenStudy (anonymous):

3?

OpenStudy (cuanchi):

(1, 1, 0, +1/2) n= principal level is the first number in the serie

OpenStudy (anonymous):

Okay thanks loads:)

OpenStudy (cuanchi):

That is not the correct answer

OpenStudy (anonymous):

So what is?

OpenStudy (cuanchi):

(3, 2, 0, -1/2)
