What does the notation '3p⁶' indicate?

Back

It indicates that there are 6 electrons in the 3p sublevel.

Front

How many electrons can the 3d sublevel hold?

Back

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.

Front

What is Hund's rule?

Back

Hund's rule states that electrons will fill degenerate orbitals singly before pairing up.
