Angular momentum L involves the revolution of a body in its orbit, not
rotation about its own axis. In the case of an electron, its mass is so low
that it exhibits particle-wave duality. In models that apply classical
mechanics to the electron (such as Bohr), only those orbitals are allowed
that consist of a whole number of wavelengths along its entire arclength.
