Best answer
Correct Answer - Option 3 : Uhlenbeek and Goudsmit

EXPLANATION:

Electron Spin:

  • S.A. Goutsmit and G.E. Uhlenbeck, in 1925, recommended that an electron has an inherent angular momentum that is a magnetic moment that is recognized as spin.
  • In atomic physics, the inherent angular momentum of a particular particle is parametrized by a spin quantum number.
  • Hence, option 3 is correct.
