Unit 2 P #6 Electron configuration and Orbital diagrams

Front

What is electron configuration?

Back

The arrangement of electrons in an atom's orbitals, which follows specific rules such as the Aufbau principle, Pauli Exclusion Principle, and Hund's Rule.

Front

What is the Aufbau principle?

Back

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

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, meaning an orbital can hold a maximum of two electrons with opposite spins.

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.
