Electron Configuration Basics

Front

What is the Aufbau Principle?

Back

The Aufbau Principle states that electrons occupy the lowest energy orbitals first before filling higher energy orbitals.

Back

1s² 2s² 2p⁶ 3s² 3p⁵.

Front

What does the term 'orbital' refer to in electron configuration?

Back

An orbital is a region in an atom where there is a high probability of finding electrons.

Front

What is the maximum number of electrons that can occupy an s orbital?

Back

An s orbital can hold a maximum of 2 electrons.

Front

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

Back

A p orbital can hold a maximum of 6 electrons.

Front

What is the significance of 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.

Front

What is the shape of a p orbital?

Back

The shape of a p orbital is dumbbell-shaped.

What is the electron configuration for Neon (Ne)?

Back

1s² 2s² 2p⁶.

Front

What is the difference between ground state and excited state of an electron?

Back

Ground state is the lowest energy state of an electron, while excited state is when an electron has absorbed energy and moved to a higher energy level.
