What does the Hund's rule primarily address regarding the filling of electrons in orbitals?

Options

  1. AThe order in which different subshells are filled.
  2. BThe pairing of electrons in degenerate orbitals.
  3. CThe maximum number of electrons in an orbital.
  4. DThe shape of orbitals.

Correct answer

B. The pairing of electrons in degenerate orbitals.

Step-by-step solution

"pairing of electrons in the orbitals belonging to the same subshell (p, d or f) does not take place until each orbital belonging to that subshell has got one electron each i.e., it is singly occupied."
