Electron Configuration- Honors Unit 4

Front

What is electron configuration?

Back

The distribution of electrons in an atom's orbitals, indicating the energy levels and sublevels occupied by electrons.

Front

What does the notation 1s² represent?

Back

It indicates that there are 2 electrons in the 1s orbital.

Front

How many electrons can occupy a single orbital?

Back

A single orbital can hold a maximum of 2 electrons.

Front

What is the maximum number of electrons in the p subshell?

Back

The p subshell can hold a maximum of 6 electrons.

Front

What is the electron configuration for Chlorine (Cl)?

Back

1s² 2s² 2p⁶ 3s² 3p⁵.

Front

What is the electron configuration for Zinc (Zn)?

Back

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰.

What is the electron configuration for Krypton (Kr)?

Back

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁶.

Front

What is the significance of the Aufbau principle?

Back

It states that electrons occupy the lowest energy orbitals first before filling higher energy levels.

Front

What is Hund's rule?

Back

Electrons will fill degenerate orbitals singly before pairing up.

Front

What is the Pauli Exclusion Principle?

Back

No two electrons in an atom can have the same set of four quantum numbers.
