Front

What is electron configuration?

Back

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

Front

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁶.

Front

What does it mean for an atom to be in an excited state?

Back

An atom is in an excited state when it has absorbed energy and one or more electrons have moved to a higher energy level.

Front

What is the Aufbau principle?

Back

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

Front

What is Hund's rule?

Back

Electrons will fill degenerate orbitals (orbitals of the same energy) singly before pairing up.

Front

What is the Pauli Exclusion Principle?

Back

No two electrons in an atom can have the same set of four quantum numbers.

Front

How many total electrons can be found in the first energy level?

Back

2 electrons.
