Electron Configuration Practice

Front

What is electron configuration?

Back

Electron configuration is 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

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.

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.

Front

What is the maximum number of electrons in an s orbital?

Back

The maximum number of electrons that can be placed in an s orbital is 2.

Front

What is the electron configuration for a Neon atom?

Back

The electron configuration for Neon is 1s² 2s² 2p⁶.

Front

What is the electron configuration for an Oxygen atom?

Back

The electron configuration for Oxygen is 1s² 2s² 2p⁴.

Front

What is the shorthand notation for electron configuration?

Back

Shorthand notation uses the nearest noble gas to represent core electrons, followed by the valence electrons.

Front

What is the electron configuration for Iron?

Back

The electron configuration for Iron is 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁶.

Front

How many electrons can fit in the p orbitals?

Back

A maximum of 6 electrons can fit in the p orbitals.
