Electron Configuration

Front

What is electron configuration?

Back

Electron configuration is the distribution of electrons in an atom's orbitals, indicating how many electrons occupy each energy level and sublevel.

Front

What is the maximum number of electrons that can occupy the s sublevel?

Back

2 electrons.

Front

How many electrons can the p sublevel hold?

Back

6 electrons.

Front

How many electrons can the d sublevel hold?

Back

10 electrons.

What is the electron configuration for an Oxygen atom?

Back

1s² 2s² 2p⁴.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in chemical bonding.

Front

How many valence electrons does an atom with the electron configuration 1s² 2s² 2p³ have?

Back

5 valence electrons.

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 (orbitals of the same energy) singly before pairing up.
