How many electrons in an atom can have quantum numbers n = 4, $ l $ = 1?

Question

Quizplus · Accepted Answer

For a given set of quantum numbers n = 4 and $ l $ = 1, the number of electrons can be determined by the formula $2(2l + 1)$. Here, $l = 1$, so the calculation is $2(2*1 + 1) = 2(3) = 6$. This accounts for the three magnetic quantum numbers ($m_l$) that $l = 1$ can have (-1, 0, +1), each of which can hold two electrons (one with spin up and one with spin down).
