What is the Pauli Exclusion Principle?

Back

The Pauli Exclusion Principle states that no two electrons in an atom can have the same set of four quantum numbers, meaning that an orbital can hold a maximum of two electrons with opposite spins.

What is an s orbital?

Back

An s orbital is a spherical region around the nucleus of an atom where there is a high probability of finding an electron. It can hold a maximum of 2 electrons.

Front

What is Aufbau's Principle?

Back

Aufbau's Principle states that electrons occupy the lowest energy orbitals first before filling higher energy levels.

Front

What is Hund's Principle?

Back

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

What is an orbital diagram?

Back

An orbital diagram is a visual representation of the arrangement of electrons in an atom's orbitals, showing the distribution of electrons among the various orbitals.
