Electron Configurations Aubin's version 1

Front

What is the Aufbau principle?

Back

The Aufbau principle states that electrons occupy the lowest energy orbitals available before filling higher energy orbitals.

Front

What is the electron configuration of an oxygen atom?

Back

1s² 2s² 2p⁴.

Front

Identify the incorrect electron configuration: 1s² 2s² 2p⁶ 3s², 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p³, 1s² 2s² 2p⁶ 3s² 3p⁶ 4s¹, 1s² 2s² 2p⁴ 3s².

Back

1s² 2s² 2p⁴ 3s² is incorrect.

Front

How many types of subshells (orbitals) are there?

Back

There are 4 different types of subshells: s, p, d, and f.

Back

1s² 2s² 2p⁶.

Front

What does Hund's rule state?

Back

Hund's rule states that electrons will fill degenerate orbitals singly before pairing up.

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.
