Quizplus · Accepted Answer

A free radical is an atom or group of atoms that has an unpaired electron in the outermost shell, which makes it highly reactive and potentially unstable. Compounds are formed by the combination of different atoms, ions are atoms or molecules with a net charge, and molecules are formed by the combination of two or more atoms bonded together.
