Electron Configuration and Orbital Diagram Practice

Front

What is electron configuration?

Back

The distribution of electrons in an atom's orbitals, indicating the energy levels and sublevels occupied by electrons.

Front

What does the notation [Ar] represent in electron configuration?

Back

It represents the electron configuration of Argon, indicating that the electron configuration of Argon is used as a reference point.

Front

How many total electrons can the p orbital hold?

Back

A p orbital can hold a maximum of 6 electrons.

Front

What is the shape of an s orbital?

Back

The shape of an s orbital is spherical.

Front

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

Back

The maximum number of electrons in the third energy level is 18.

Front

What is a Lewis dot structure?

Back

A diagram that represents the valence electrons of an atom as dots around the element's symbol.

Front

What is the significance of the Aufbau principle?

Back

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

Front

What is Hund's rule?

Back

Hund's rule states that electrons will fill degenerate orbitals singly before pairing up.

Front

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

Back

The ground state is the lowest energy configuration of an atom, while the excited state has one or more electrons in higher energy levels.

Front

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

Back

The element is Chlorine.
