Best Answer: If an atom gains or loses electrons, it is no longer neutral, so it becomes charged. If it GAINS an electron, it gains an extra -1 charge. If it LOSES an electron, it now has a +1 charge. When an atom loses or gains electrons, it is now called an ion. If it loses an electron, it's called a cation, if it gains an electron, its called an anion.
When an atom gains extra electrons, it becomes a negatively charged ion. If it has only one extra electron, its charge is -1. If it gains two extra electrons, its charge is -2, and so on. These charges are indicated by superscripts that follow the symbol of the atom. Note the conventions illustrated here.
