electron configurations and orbital notation

Front

What is an electron configuration?

Back

An 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 orbital notation?

Back

Orbital notation is a way of representing the arrangement of electrons in an atom using arrows to indicate the spin of electrons in orbitals.

What is the electron configuration for oxygen?

Back

1s² 2s² 2p⁴.

Front

What is the electron configuration for fluorine?

Back

1s² 2s² 2p⁵.

Front

How many electrons can the p orbital hold?

Back

The p orbital can hold a maximum of 6 electrons.

Front

What is the maximum number of electrons in the s orbital?

Back

The s orbital can hold a maximum of 2 electrons.

What element has the electron configuration 1s² 2s² 2p⁶?

Back

Neon.

Front

What is the significance of the Aufbau principle?

Back

The Aufbau principle states that electrons occupy the lowest energy orbitals first before moving to 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.

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.
