• s orbital

• p orbital

• d orbital

• f orbital

Which of the following statements about atomic orbitals is TRUE?

• An atomic orbital can hold any number of electrons.

• An atomic orbital can only hold one electron.

• An atomic orbital defines a region where an electron is most likely to be found.

• An atomic orbital has a specific size and shape.

How many sublevels does the energy level with n = 3 have?

• 1

• 2

• 3

• 4

Which of the following factors is NOT considered when writing electron configuration?

• Principal quantum number (n)

• Azimuthal quantum number (l)

• Spin quantum number (ms)

• Pauli Exclusion Principle

The ground state electron configuration describes the distribution of electrons in an atom at its:

• highest energy level

• lowest energy level

• middle energy level

• specific energy level

What principle states that electrons fill orbitals with the lowest energy levels first?

• Pauli Exclusion Principle

• Aufbau Principle

• Hund's Rule

• Noble Gas Rule

According to the Pauli Exclusion Principle, which of the following statements is FALSE?

• An orbital can hold a maximum of two electrons.

• Two electrons in the same orbital must have opposite spins.

• No two electrons can have the same set of four quantum numbers.

• All orbitals in a subshell must be filled before moving to a higher energy level.

When filling degenerate orbitals, Hund's Rule states that electrons first fill each orbital:

• completely before moving to the next

• halfway before pairing up

• with the same spin

• with the same energy

• They show the order in which electrons fill the orbitals.

• They use numbers (1, 2, 3, ...) to represent the energy levels.

• 1. They can be used to predict the reactivity of an element.
