Electron Configurations & Orbital Notation

Front

What is the Aufbau Principle?

Back

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

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

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 the same orbital.

Front

How many electrons can the p sublevel hold?

Back

The p sublevel can hold a maximum of 6 electrons.

Front

How many electrons can the d sublevel hold?

Back

The d sublevel can hold a maximum of 10 electrons.

Front

How many electrons can the f sublevel hold?

Back

The f sublevel can hold a maximum of 14 electrons.

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 orbitals.

Front

What does an upward arrow represent in an orbital diagram?

Back

An upward arrow represents an electron with a spin of +1/2.

Front

What does a downward arrow represent in an orbital diagram?

Back

A downward arrow represents an electron with a spin of -1/2.

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.
