Electron Configuration Pre-AP

What does the Aufbau Principle state?

• A maximum of two electrons can occupy a single atomic orbital, but if only if the electrons have opposite spins.
• Each electron occupies the lowest energy orbital available.
• Single electrons with the same spin must occupy each suborbital before additional electrons with opposite spins can occupy the same suborbital.
• All of these.

What does the Pauli Exclusion Principle state?

• A maximum of two electrons can occupy a single atomic orbital, but if only if the electrons have opposite spins.
• Each electron occupies the lowest energy orbital available.
• Single electrons with the same spin must occupy each suborbital before additional electrons with opposite spins can occupy the same suborbital.
• All of these.

What does Hund's Rule state?

• A maximum of two electrons can occupy a single atomic orbital, but if only if the electrons have opposite spins.
• Each electron occupies the lowest energy orbital available.
• Single electrons with the same spin must occupy each suborbital before additional electrons with opposite spins can occupy the same suborbital.
• All of these.
