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

What does the notation '1s2' represent?

Back

It indicates that there are 2 electrons in the 1s orbital.

Front

How many electrons can the p orbital hold?

Back

Front

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

Back

A d orbital can hold a maximum of 10 electrons.

Front

What is the significance of the Aufbau principle?

Back

It states 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 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.
