Chap. 4-5 Test Review

Front

What is an s orbital?

Back

An s orbital is a spherical region around the nucleus of an atom where there is a high probability of finding an electron. It can hold a maximum of 2 electrons.

Front

What is a p orbital?

Back

A p orbital is a dumbbell-shaped region around the nucleus of an atom where there is a high probability of finding an electron. It can hold a maximum of 6 electrons.

Front

What is a d orbital?

Back

A d orbital is a more complex shaped region around the nucleus of an atom where there is a high probability of finding an electron. It can hold a maximum of 10 electrons.

Front

What is an f orbital?

Back

An f orbital is a complex shaped region around the nucleus of an atom where there is a high probability of finding an electron. It can hold a maximum of 14 electrons.

Front

What is the Aufbau Principle?

Back

The Aufbau Principle states that electrons fill the lowest energy orbitals first before occupying higher energy levels.

Front

What is the Pauli Exclusion Principle?

Back

The Pauli Exclusion Principle states that no two electrons in an atom can have the same set of four quantum numbers.

Front

What is Hund's Rule?

Back

Hund's Rule states that electrons will occupy degenerate orbitals singly before pairing up in the same orbital.
