Question

The quantum number +1/2 and -1/2 for the electron spin represent

Answer 1

Magnetic Spin Quantum number (ms)

This quantum number describes the nature of spin of an electron in its orbital. There are only two possible ways in which an electron can spin on its orbit either clockwise or anti-clockwise.

The clockwise motion is represented by +1/2 while the anticlockwise rotation is represented by -1/2.
