Electron Configuration Review

Front

What is electron configuration?

Back

Electron configuration is the distribution of electrons in an atom's orbitals, indicating how many electrons occupy each energy level and sublevel.

What is the significance of the Aufbau principle?

Back

The Aufbau principle states that electrons occupy the lowest energy orbitals first before filling higher energy levels.

Front

What is Hund's rule?

Back

Hund's rule states that electrons will fill degenerate orbitals (orbitals of the same energy) singly before pairing up.
