Question

Which of the following is a possible set of quantum numbers for an electron?

(1, 0, 0, +1)
(2, 2, 1, +½)
(4, -3, 0, -½)
(3, 2, 1, -½)

Answer 1

the \(l\) quantum number varies from \(0\) to \((n-1)\) the 2nd and 3rd options don't follow this rule and get eliminated
the \(s\) quantum number can be either \(\large +\frac{1}{2}\) or \(\large -\frac{1}{2}\) this eliminates option 1
so we are left with option 4 which is the correct answer
