What is Plasma? | MIT Plasma Science and Fusion Center
WEBPlasma is superheated matter – so hot that the electrons are ripped away from the atoms forming an ionized gas. It comprises over 99% of the visible universe. In the night sky, plasma glows in the form of stars, nebulas, and even the auroras that sometimes ripple above the north and south poles.

DOE Explains...Plasma | Department of Energy
WEBIn plasma, some of the electrons separate and become free from neutral atoms (atoms that have an equal number of protons and electrons and thus a neutral charge). The resulting free electrons makes plasma different from the other states of matter, where the electrons are held close to nuclei .

WEBIt consists of a collection of free-moving electrons, positive ions and neutral particles. Although it is closely related to the gas phase in that it has no definite shape or volume, it does differ in a number of ways: Plasma has a very high electrical conductivity. Plasma is more readily influenced by electric and magnetic fields than by gravity.

WEBNov 25, 2001 · Plasma is sometimes called "the fourth state of matter", beyond the familiar three--solid, liquid and gas. It is a gas in which atoms have been broken up into free-floating negative electrons and positive ions, atoms which have lost electrons and are left with a positive electric charge.
