Question: what is an ion?
Answer: An ion is an atom or group of atoms that has a net positive or negative charge. They are formed when atoms lose or gain electrons. If a neutral atom loses one or more electrons, it has a net positive charge and is known as a cation. If an atom gains electrons, it has a net negative charge and is known as an anion.
