Answer:

The plasma state is a gaseous mixture of positive ions and electrons. Plasmas can be fully ionized, as the plasma in the Sun, or partially ionized, as in fluorescent lamps, which contain a large number of neutral atoms.

Plasma is a state of matter that is often thought of as a subset of gases, but the two states behave very differently. Like gases, plasmas have no fixed shape or volume, and are less dense than solids or liquids. But unlike ordinary gases, plasmas are made up of atoms in which some or all of the electrons have been stripped away and positively charged nuclei, called ions, roam freely. "A gas is made of neutral molecules and atoms," said Xuedong Hu, a professor of physics at the University at Buffalo. That is, the number of negatively charged electrons equals the number of positively charged protons. "Plasma is a charged gas, with strong Coulomb [or electrostatic] interactions," Hu told Live Science. Atoms or molecules can acquire a positive or negative electrical charge when they gain or lose electrons. This process is called ionization. Plasma makes up the sun and stars, and it is the most common state of matter in the universe as a whole. (Blood plasma, by the way, is something completely different. It is the liquid portion of blood. It is 92 percent water and constitutes 55 percent of blood volume, according to the American Red Cross.)
