The electronic configuration for degenerate orbitals is explained by:
Correct answer: C. Hund's Rule
- A. Aufbau Principle
- B. n+I Rule
- C. Hund's Rule
- D. Pauli's Exclusion Principle
Explanation
According to Hund's rule every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.

About Electronic Configuration
Electronic configuration describes how electrons occupy shells, subshells and orbitals around an atom. Questions use the Aufbau principle, Pauli exclusion principle and Hund's rule to write configurations, identify valence electrons, form ions and explain periodic trends, including common exceptions such as chromium and copper.
