Question

The spin quantum numbers + 1/2 and - 1/2 for the electron represents:

• A. rotation of electron in clockwise and anticlockwise direction respectively
• B. shape of the orbital
• C. size of the orbital
• D. rotation of electron in one direction only

Answer 1

The correct option is A rotation of electron in clockwise and anticlockwise direction respectively

By convention an electron with +1/2 spin is considered as rotating clockwise and that with -1/2 spin is considered as rotating anti-clockwise.
