Orbital Diagrams and Electron Configuration 2024

Front

What is an orbital diagram?

Back

An orbital diagram is a visual representation of the electron configuration of an atom, showing the distribution of electrons in atomic orbitals.

Front

What is electron configuration?

Back

Electron configuration is the arrangement of electrons in an atom's orbitals, typically represented using notation that indicates the energy levels and sublevels.

Front

What does the Aufbau Principle state?

Back

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

Front

What is Hund's Rule?

Back

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

Front

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

Front

What is the maximum number of electrons in the first energy level?

Back

The maximum number of electrons in the first energy level is 2.

Front

How many energy levels can an atom have?

Back

An atom can have a maximum of 7 energy levels.
