Electron Configuration

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

What is the maximum number of electrons that can occupy a single orbital?

Back

2 electrons, due to the Pauli exclusion principle.

Front

What is the Aufbau principle?

Back

Electrons fill orbitals starting from the lowest energy level to the highest.

Front

What is the Pauli exclusion principle?

Back

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

Front

What is Hund's rule?

Back

Electrons will occupy degenerate orbitals singly before pairing up.

Front

What is a Lewis dot model?

Back

A diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist in the molecule.
