If you remove an electron, which has a negative charge, from an atom you produce an ion, which has a positive charge. A plasma is a gas which has a substantial percentage of ions and electrons (charged particles) present (that percentage can be anything from ~5-100%). Typically plasmas are produced by adding energy to a gas until it "breaks down" - that is a sufficient number of electrons and ions are produced. Plasmas are sometimes referred to as the "4th state of matter" - since adding energy (heat) to a solid gives you a liquid, if you continue to add energy you get a gas, and finally a plasma. It's not *quite* as straightforward as that, but the principle is right. In order to keep the ions and electrons separate and stop them coming back together some form of energy must be continually supplied. Typically plasmas glow, because some of the energy they absorb is turned into light by collisions between electrons and neutral atoms.

Plasma (physics), fluid made up of electrically charged atomic particles (ions and electrons). It has specific properties that make its behaviour markedly different from that of other states of matter, such as gases.

Matter as we see it around us consists of atoms, which are the building blocks of solids, liquids, and gases. Plasma, often called the fourth state of matter, is formed when atoms, instead of being combined into more complex structures, are broken up into their main constituent parts. This happens in natural environments such as the stars, where the temperature is very high, greater than tens of thousands, or even millions, of degrees. The plasma state of matter is also of great importance to controlled nuclear fusion, which is a potential future energy source. The physical laws that govern plasmas are important both for understanding astrophysical phenomena and for controlling the generation and release of nuclear energy by fusion processes.

Plasma is a highly ionized gas in which the number of free electrons is approximately equal to the number of positive ions. Sometimes described as the fourth state of matter, plasmas occur in interstellar space, in the atmospheres of stars (including the sun), in discharge tubes, and in experimental thermonuclear reactors.

Plasma is a fluid of charged particles. The electrons have been stripped from the atoms leaving ions in the material. It occurs naturally in lightning and nuclear reactions.

Plasma is basically matter that is so hot that it has been stripped of its electrons. So it could be made up of anything really.
