Electron Configuration Quiz

What is orbital notation?

• A way of representing the electron configuration of an atom using arrows and numbers.

• A system for representing the arrangement of atoms in a molecule.

• A technique for mapping the trajectory of a satellite in space.

• A method of visualizing the movement of planets in the solar system.

State the Aufbau principle.

• Electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels.

• Electrons fill atomic orbitals randomly without any specific order.

• Electrons fill atomic orbitals of the highest available energy levels before occupying lower levels.

• Electrons fill atomic orbitals of the same energy level simultaneously.

What is Hund's rule?

• Hund's rule states that electrons occupy orbitals of different energy levels one at a time before pairing up.

• Hund's rule states that electrons occupy orbitals of the same energy level all at once.

• Hund's rule states that electrons do not occupy orbitals and instead exist in a free state.

• Hund's rule states that electrons occupy orbitals of the same energy level one at a time before pairing up.

Explain the Pauli exclusion principle.

• No two identical fermions can occupy the same quantum state simultaneously.

• The Pauli exclusion principle is a concept in classical mechanics, not quantum mechanics.

• The Pauli exclusion principle only applies to bosons, not fermions.

• The Pauli exclusion principle states that identical fermions can occupy the same quantum state simultaneously.
