Electron Configuration Quiz

What is the maximum number of electrons that can occupy a single orbital according to the Pauli Exclusion Principle?

• 1

• 2

• 3

• 4

According to Hund's Rule, how are electrons distributed in orbitals of the same energy?

• Electrons fill each orbital singly before any orbital gets a second electron.

• Electrons pair up in each orbital before filling the next orbital.

• All electrons in a subshell must have the same spin.

• Electrons fill the highest energy orbitals first.

What is the correct electron configuration for Carbon (C)?

Which principle states that electrons fill the lowest energy orbitals first?

• Hund's Rule

• Pauli Exclusion Principle

• Aufbau Principle

• Heisenberg Uncertainty Principle

How many electrons can the d subshell hold?

• 2

• 6

• 10

• 14

What does the Pauli Exclusion Principle specifically state about electrons in an atom?

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

• Electrons must have opposite spins to share an orbital.

• Electrons fill the lowest energy orbitals available.

• Electrons in the same orbital must have the same spin.

Which of the following elements will have a partially filled d subshell in its ground state?

• Sodium (Na)

• Magnesium (Mg)

• Iron (Fe)

• Neon (Ne)

What is the electron configuration of Oxygen (O)?

According to Hund's Rule, if three electrons were to occupy p orbitals, how would they be distributed?

• All three electrons would occupy a single p orbital with parallel spins.

• Each electron would occupy separate p orbitals with parallel spins.

• Two electrons would pair up in one orbital, and the third would occupy a different orbital.

• Electrons would randomly distribute among the p orbitals without regard to spin.
