In this video I will explain what is the spin quantum number ms=? We can obtain 3 quantum numbers; n (principle quantum number),l (angular momentum of the electron in a hydrogen atom), and ml (associated with the orientation of the angular momentum when the hydrogen is placed in a magnetic electric field); related to the Schrodinger number the define the motion, position, and angular momentum...of an electron in a hydrogen atom. There is also a 4th quantum number ms, spin quantum number.
