Definition: the phase of matter where particles at extremely high temperatures become ionized. example: the state of matter of the interior of the sun and other stars.

Plasma

Explanation:

Plasma is a state of matter that in some cases is a synonym of ionized gas. It consists of groups of ions (particles with a net charge) with some of their outer electrons removed.

How many electrons have been removed depends on the type of plasma, since the most energetic plasmas are completely free of orbiting electrons. This is the case of the interiors of the sun and other stars.
