Electron Configurations

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds with other atoms.

Front

Front

What does the noble gas electron configuration [Xe] 6s² 4f¹⁴ 5d⁹ represent?

Back

This configuration represents the element Gold (Au).

Front

What is the electron configuration for Chlorine (Cl)?

Front

Which element has the electron configuration [Ne] 3s² 3p⁵?

Back

Chlorine.

Front

What is the significance of noble gas configurations in electron configurations?

Back

Noble gas configurations simplify the representation of electron arrangements by using the nearest noble gas to represent inner shell 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 atomic orbitals.

Front

Which element is represented by the orbital diagram with 6 electrons in the outer shell?

Back

The element is Oxygen.

Front

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

Back

A single orbital can hold a maximum of 2 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.
