Quizplus · Accepted Answer

According to the quantum mechanical model of the hydrogen atom, the ground state electron is in the lowest energy level (n=1) and has an angular momentum quantum number, ℓ, of 0. This means that the electron is in an s-orbital, which has no angular nodes and no angular momentum. Therefore, the ground state electron has zero orbital angular momentum.
