Sometimes a flash of high voltage, or heating to extreme temperature will cause the 'outermost' electrons to get knocked off. These electrons will then knock off electrons from neighbouring atoms. This creates a mass of ionized matter, which is called plasma. Plasma is considered the 4th state of matter. The other three states of matter are solids, liquids and gases, all of which are neutral in normal conditions. The plasma state is similar to the gaseous state, and yet it is very different.
