Electron Configuration Practice

Front

What is electron configuration?

Back

Electron configuration is the distribution of electrons in an atom's orbitals, indicating the energy levels and sublevels occupied by electrons.

Front

What is the significance of the Aufbau principle in electron configuration?

Back

The Aufbau principle states that electrons occupy the lowest energy orbitals first before filling higher energy levels.

Front

What does the Pauli Exclusion Principle state?

Back

The Pauli Exclusion Principle states that no two electrons in an atom can have the same set of four quantum numbers.

Front

What is Hund's Rule?

Back

Hund's Rule states that electrons will fill degenerate orbitals singly before pairing up in the same orbital.

Front

How many electrons can the s sublevel hold?

Back

The s sublevel can hold a maximum of 2 electrons.

Front

How many electrons can the p sublevel hold?

Back

The p sublevel can hold a maximum of 6 electrons.
