In this video I will calculate the spin angular momentum=? We discover there are 2 components to the angular momentum. There are the orbital motion of the electron contributing to the angular momentum and there is also a “spin concept,” or the spin angular momentum, S. S in the electron never changes and is always S=1/2.
