Detailed explanation-1: -An atom that gains one or more electrons will exhibit a negative charge and is called an anion. Positively charged atoms called cations are formed when an atom loses one or more electrons.

Detailed explanation-2: -Ions are formed when an atom lose or gain electrons. Ions are atoms that have a positive or negative charge because they have unequal numbers of protons and electrons.

Detailed explanation-3: -Explanation: When an atom gains/loses an electron, the atom becomes charged, and is called an ion. Gaining an electron results in a negative charge, so the atom is an anion. Losing an electron results in a positive charge, so atom ion is a cation.
