What are 4 quantum numbers for sulfur?

Question

Sulfur has the electron configuration of 1s^2 2s^2 2p^6 3s^2 3p^4. We have to write a set of 4 quantum numbers for the 2 unpaired electrons

Answer 1

The two unpaired electrons are in the outermost sublevel, 3p.

Since the sublevel is 3p, we can see that the principal quantum number (n) = 3.

The angular quantum number (l) that corresponds with sublevel p is 1.

When l = 1, possible values for quantum number m_l are -1, 0 and +1.

The value of quantum number m_s can only be +1/2 or -1/2, denoting either a clockwise or counter-clockwise spin on the electron. Since those last two electrons are unpaired, they will have the same spin, and thus the same value for m_s
