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 subshell.

What is the electron configuration of Copper (Cu)?

Back

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁹.

Front

How many types of subshells (orbitals) are there?

Back

There are 4 types of subshells: s, p, d, and f.

Front

What is the maximum number of electrons that can occupy a p orbital?

Back

A p orbital can hold a maximum of 6 electrons.

Front

What is the electron configuration of an oxygen atom?

Back

Front

What is the maximum number of electrons in a d subshell?

Back

A d subshell can hold a maximum of 10 electrons.

Front

What is the Aufbau principle?

Back

The principle 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 (orbitals of the same energy) 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.
