WebThe free negative electrons and positive ions in a plasma allow electric current to flow through it. In a plasma, some electrons are freed from their atoms, allowing current and electricity to flow and can react to, both, electric and magnetic fields. This is a very useful characteristic as you’ll see later... WebA positive ion is formed when (a) a valence electron breaks away from the atom (b) there are more holes than electrons in the outer orbit (c) two atoms bond together (d) an atom gains an extra valence electron
