What is Electron Configuration?

Back

The distribution of electrons in an atom's orbitals, indicating how electrons are arranged around the nucleus.

Front

What is the Aufbau Principle?

Back

A rule stating that electrons occupy the lowest energy orbitals first before filling higher energy levels.

Front

What is the Pauli Exclusion Principle?

Back

A principle stating that no two electrons in an atom can have the same set of four quantum numbers.

Front

What is Hund's Rule?

Back

A rule stating that electrons will fill degenerate orbitals (orbitals of the same energy) singly before pairing up.
