The electronic configuration for degenerated orbitals is explained by

Correct answer: C. Hunds rule

  • A. Aufbau principle
  • B. N + l rule
  • C. Hunds rule
  • D. Pauli exclusion principle

Explanation

In 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 Atomic Structure

Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
