What is the maximum number of electrons that can occupy the orbitals with azimuthal quantum number = 3?

Question

Quizplus · Accepted Answer

The azimuthal quantum number, also known as the angular momentum quantum number or orbital quantum number, determines the shape of the orbital. It is denoted by $l$ and can have values from 0 to $n-1$, where $n$ is the principal quantum number. For $l = 3$, we are dealing with f orbitals. Each orbital can hold 2 electrons (one with spin up and one with spin down), and since there are 7 f orbitals for a given energy level ($l = 3$), the maximum number of electrons is $7 \times 2 = 14$.
