Detailed explanation-1: -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.

Detailed explanation-2: -Definition: An ion is an atom or molecule which has lost or gained one or more electrons, and carries a net electric charge. If the result is an atom with more electrons than protons, the ion is negatively charged.

Detailed explanation-3: -An ion is an atom or group of atoms that has an electric charge. Ions with a positive charge are called cations. Ions with a negative charge are called anions. Many normal substances exist in the body as ions. Common examples include sodium, potassium, calcium, chloride, and bicarbonate.

Detailed explanation-4: -An atom that gains electrons becomes a negatively-charged ion called an anion or electronegative ion.

Detailed explanation-5: -Ions-an ion is an atom or molecule which has gained or lost electrons.
