Lesson Summary
... This seems to work well for neutral atoms, what about ions? Remember that a cation is formed when electrons are removed from a neutral atom and anions are formed when electrons are added to a neutral atom. But where do the electrons get added to or removed from? The electrons that are involved in ch ...
