Plasma is a state of matter consisting of a collection of free-moving electrons and ionized atoms or molecules, which are atoms or molecules that have lost or gained electrons and thus have a net positive or negative charge. This state occurs at high temperatures or through other processes that strip electrons from atoms, creating a mixture of charged particles.
