• Rutherford Model

• Quantum Number

• Atomic Orbital

• Dalton Model

What are the different atomic orbitals?

• f, e, w, h

• a, b, c, d

• p, s, a, t

The ways in which electrons are arranged in various orbitals around the nuclei of atoms are called _____.

• Electron Configurations

• Electron Choreography

• Electron Chromatography

• Electron Positions

Electrons occupy the orbitals of lowest energy level first. The orbitals for any sublevel of a prinicipal energy level are always of equal energy. Within a principal energy level, the s sublevel is always the lowest-energy sublevel.

This describes _____.

• the Pauli Exclusion Principle

• Hund's Rule

• the Aufbau Princple

• the Schrodinger Principle

An atomic orbital may describe at most two electrons. To occupy the same orbital, two electrons must have opposite spins.
