Plasma - ionized gas that has some electrons that are described as free because they are not bound to an atom or molecule specific gravity - measurement of the density of substances in a liquid compared to water atomic theory - a theory that states that all matter is composed of tiny particles called atoms. John Dalton - developed modern atomic theory negative ion - anion, gains electrons positive ion - cation; loses electrons
