Electron Configuration and Orbital Notation

Front

What is electron configuration?

Back

The distribution of electrons in an atom's orbitals, indicating the energy levels and sublevels occupied by electrons.

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.

Front

What is the noble gas shorthand notation?

Back

A method of writing electron configurations using the nearest noble gas to simplify the representation.
