Electron Configurations beyond Neon (8.1.4)

Question 1

• Each orbital holds two electrons, the s orbital for a given energy level is lower in energy than the p orbitals, and one electron enters each degenerate orbital before any pairing occurs.

Answer 1

• Each orbital holds two electrons, the s orbital for a given energy level is lower in energy than the p orbitals, and one electron enters each degenerate orbital before any pairing occurs.
