Why are atoms attracted to each other in an ionic bond?

The answer is C. Inversely, when this atom gains a positively charged ion. (The atom) becomes a negatively charged atom or an "anion".

Explanation:

Since electrons are negatively charged, an atom that loses one or more electrons will become positively charged, an atom that gains one or more electrons becomes negatively charged. The oppositely charged ions attract each other to form ionic networks (or lattices)

opposite charges attract

Explanation: Ionic bonding is the attraction between positive and negative charge ions electrostatics explains why this happens: opposite charges attract and like charges repel. when many ions attract each other, they form large, ordered, crystal lattices in which each ion is surrounded by ions of the opposite charge.
