ionisation

Making atoms charged

Ionisation is the British spelling of ionization—the process of converting atoms or molecules into ions by adding or removing electrons.

This happens through radiation, heat, or chemical reactions.

In physics and chemistry, ionisation energy is the amount required to remove an electron from an atom: The ionisation of gases in the upper atmosphere creates auroras.
