Honors Chemistry Unit 3 Review

Front

What does Hund's Rule state?

Back

Hund's Rule states that electrons enter orbitals with the same energy such that as many electrons have the same spin as possible.

Front

How many dots are shown in the Lewis dot structure for Sulfur?

Back

Sulfur will have two dots on the left-hand side, two on the top, one on the right-hand side, and one on the bottom of the symbol.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the highest occupied energy level of the atom.

Front

What are degenerate orbitals?

Back

Degenerate orbitals are orbitals that have the same energy.

Front

What is the electron configuration for Nitrogen?

Back

Nitrogen has the electron configuration 1s² 2s² 2p³.

Front

Define 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 the Aufbau Principle?

Back

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

Front

What is the significance of the Heisenberg Uncertainty Principle?

Back

The Heisenberg Uncertainty Principle states that it is impossible to know both the position and momentum of an electron simultaneously.

Front

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

Back

The maximum number of electrons in an s orbital is 2.

Front

What is the shape of p orbitals?

Back

The shape of p orbitals is dumbbell-shaped.
