Orbital Diagrams and Electron Configurations

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

How many electrons can the s sublevel (orbital) hold?

Back

2 electrons.

Front

What is the maximum number of electrons that a p orbital can hold?

Back

6 electrons.

Front

What is the electron configuration for a Neon (Ne) atom?

Back

1s² 2s² 2p⁶.

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 Hund's rule?

Back

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

What is the shorthand electron configuration for Argon (Ar)?

Back

[Ne] 3s² 3p⁶.

Front

How do you determine the number of valence electrons in an atom?

Back

The number of valence electrons is determined by the group number of the element in the periodic table.
