Orbitals & Orbital Notation

Flashcards covering key concepts from the lecture on orbitals and orbital notation.

Orbital

A region in an atom where there is a high probability of finding electrons.

Pauli’s Exclusion Principle

States that in order for two electrons to share the same orbital, they must be of opposite spin.

Hund’s Rule

States that electrons in the same sublevel occupy empty orbitals first before pairing up.

Aufbau Principle

States that electrons are added one at a time to the lowest energy level available.

Principal Energy Level (PEL)

The energy levels of an atom, represented by n = 1-7.

Sublevel

The s, p, d, & f regions within each principal energy level, each with a different shape and number of orbitals.

Electron Configuration

The arrangement of electrons within an atom.
