Honors Electron Configuration Test

Front

What is electron configuration?

Back

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

What is the electron configuration for Arsenic (As)?

Back

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p³

What is the electron configuration for Aluminum (Al)?

Back

1s² 2s² 2p⁶ 3s² 3p¹

Front

How does the electron configuration change for an anion?

Back

For an anion, electrons are added to the outermost shell, increasing the total number of electrons.

What is the electron configuration for As⁻²?

Back

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p⁵

Front

What is the significance of the noble gas notation in electron configuration?

Back

Noble gas notation simplifies electron configurations by using the electron configuration of the nearest noble gas to represent inner shell electrons.

Front

What element has the electron configuration [Kr] 5s² 4d⁵?

Back

Technetium (Tc)

Front

What is the electron configuration for Selenium (Se)?

Back

[Ar] 4s² 3d¹⁰ 4p⁴

Front

What is the Aufbau principle?

Back

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

Front

What is Hund's rule?

Back

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