Bad Qubits — Learn Quantum by Doing

Multiple choice

The lesson notes the Bohr model gets hydrogen's energy levels right but is wrong about the ground state's angular momentum. What does full quantum mechanics give for the angular momentum of the hydrogen ground state?

L = 0 (it is an s state with no orbital angular momentum)
L = 2*hbar
L = hbar, as the Bohr model assigns to the n=1 orbit
L = 13.6*hbar
