Answer to Question 1

c.
The Pauli exclusion principle states that no two electrons in an atom may have the same set of quantum numbers (n, l, ml, ms). Therefore, each nl subshell can hold 2(2l + 1) electrons. The orbital angular momentum quantum number in this case is 5, so the total number of electrons is then
