Explain the quantum number s.

Explanation

Spin quantum number:describes the spin orientation of the electrons. It is denoted by `m_(s).` The electrons can orientate only in two ways either clockwise or anticlockwise. These two orientations are represented by `+ (1)/(2) and -(1)/(2) .`These two orientations are called two spin states of the electron and represented by two arrows `uarr` (spin up) and `darr` (spin down),
