Electron Configuration

Front

What is electron configuration?

Back

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

Front

How many electrons can be found in a p orbital?

Back

A p orbital can hold a maximum of 6 electrons.

Front

What is the electron configuration for an oxygen atom?

Back

1s² 2s² 2p⁴.

Front

What is the Pauli Exclusion Principle?

Back

No two electrons in an atom can have the same set of four quantum numbers; electrons must have opposite spins when occupying the same orbital.

Front

What is Hund's Rule?

Back

Electrons will fill degenerate orbitals (orbitals of the same energy) singly before pairing up.

Front

What is the Aufbau Principle?

Back

Electrons occupy the lowest energy orbitals first before filling higher energy orbitals.

Front

What is the maximum number of electrons in the third energy level?

Back

The third energy level can hold a maximum of 18 electrons.

Front

What atom has the electron configuration 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰?

Back

Zinc.

Front

What is the shape of an s orbital?

Back

An s orbital has a spherical shape.

Front

What is the shape of a p orbital?

Back

A p orbital has a dumbbell shape.
