Using what you know about valence electrons, chemical reactions, and full outer shells of electrons: Hydrogen has one electron, helium has two electrons, and lithium has three electrons. Hydrogen and lithium are both reactive, but helium is nonreactive. How can electrons be used to explain this pattern of behavior?
