We´re asked to determine how many electrons are in a set of quantum numbers given. To solve this problem, let’s first define and determine the possible values of the four quantum numbers:

principal quantum number (n)  energy level in orbitals and its value could be any positive integer starting from 1 to infinity.

angular momentum quantum number () → (l) has to be at least 1 less than n, range of values from 0 up to (n-1)

Each  value corresponds to a subshell:
