Detailed explanation-1: -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-2: -An ion that has more electrons than protons, giving it a net negative charge, is named an anion, and a minus indication “Anion (−)” indicates the negative charge.

Detailed explanation-3: -A cation is an ion with positive charge, which means it has more protons (positively-charged particles) than electrons (negatively-charged particles). Cations are formed when an atom loses one or more electrons: the loss of the negatively-charged electron(s) results in an overall positive charge.

Detailed explanation-4: -An ionic bond is formed by the complete transfer of some electrons from one atom to another. The atom losing one or more electrons becomes a cation-a positively charged ion. The atom gaining one or more electron becomes an anion-a negatively charged ion.
