Which electron configuration rule is responsible for the maximum possible extent of single occupation of degenerate orbitals?

Options

  1. APauli's exclusion principle
  2. BAufbau principle
  3. CHund's rule
  4. DHeisenberg's uncertainty principle

Correct answer

C. Hund's rule

Step-by-step solution

The lowest energy state corresponds to the maximum possible extent of single occupation of orbital and parallel spins, which is explained by Hund's rule.
