CHAPTER 2
... Atoms are built of a nucleus and electrons orbiting around the nucleus. An atom may loose or gain one or more electrons – the resulting particle is called an ION If the atom loses electron(s), it becomes a cation (positively charged) If the atom gains electron(s), it becomes an anion (positively cha ...
