An ionic bond is a bond in which:

• A. Atoms share electrons
• B. Atoms share a proton.
• C. Atoms of opposite charges attract each other

Answer: (C)

Verified step by step guidance

1. Understand that an ionic bond is a type of chemical bond formed through the electrostatic attraction between oppositely charged ions.
2. Recognize that ions are atoms or molecules that have gained or lost one or more electrons, resulting in a net positive or negative charge.
3. Identify that in an ionic bond, one atom donates an electron to another atom, leading to the formation of a cation (positively charged ion) and an anion (negatively charged ion).
4. Acknowledge that the attraction between the cation and anion due to their opposite charges is what constitutes the ionic bond.
5. Differentiate ionic bonds from covalent bonds, where atoms share electrons rather than transferring them.
