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

Options

  1. Arotation of the electron in clockwise and anticlockwise direction respectively
  2. Brotation of the electron in anticlockwise and clockwise direction respectively
  3. Cmagnetic moment of the electron pointing up and down respectively
  4. Dtwo quantum mechanical spin states which have no classical analogues

Correct answer

D. two quantum mechanical spin states which have no classical analogues

Step-by-step solution

The quantum numbers + 1 2 and - 1 2 indicate the rotation of electrons around its axis in opposite directions. Hence, they represent the two quantum mechanical spin states which have no classical analogues.
