Answer 2

Explanation:

An ion is a particle, atom or molecule with a net electrical charge. The charge of the electron is considered negative by convention. The negative charge of an electron is equal and opposite to charged proton considered positive by convention.

Common examples include sodium, potassium, calcium, chloride, and bicarbonate.

Ions are formed when atoms lose or gain electrons in order to fulfill the octet rule and have full outer valence electron shells. When they lose electrons, they become positively charged and are named cations. When they gain electrons, they are negatively charged and are named anions.
