A plasma is a state of matter(akin to solid, liquid and gas) where the matter has become ionized, or the electrons stripped from the atoms. Therefore, a plasma consists of both negatively charged electrons, and positively charged ions. | A plasma is a state of matter(akin to solid, liquid and gas) where the matter has become ionized, or the electrons stripped from the atoms.
