MCQ
The fine structure of hydrogen spectrum can be explained by:
  • A
    the presence of neutrons in the nucleus.
  • B
    the finite size of nucleus.
  • C
    the orbital angular momentum of electrons.
  • D
    the spin angular momentum of electrons.

Answer

  1. the spin angular momentum of electrons.

Explanation:

The fine structure describes the splitting of the spectral lines of atoms due to electron spin angular momentum.
