The region around the nucleus of an atom where an electron is likely to be moving.

• quantum

• atomic orbitals

• photons

• energy level

An atomic orbital may describe at most two electrons.

• Pauli exclusion principle

• Aufbau principle

• Hund’s rule

• electron configurations

The regions within which electrons have the highest probability of being found.

• Aufbau principle

• electron configurations

• atomic orbitals

• photons

When electrons occupy orbitals of equal energy, one electron enters each orbital until all the orbitals contain one electron.
