Question

The quantum numbers of $+1/2$ and $-1/2$ for the electron spin represents________.

• A. rotation of electron in clockwise and anticlockwise direction respectively
• B. rotation of electron in anticlockwise and clockwise direction respectively
• C. two quantum mechanical states having classical analogue
• D. two quantum mechanical states having no classical analogue

Answer 1

The correct option is D two quantum mechanical states having no classical analogue

The two quantum numbers of spin states $+1/2$ and $-1/2$ represents the opposite spin of electrons in an orbital.
