The strength of an ionic bond comes principally from:

• A. The converting of atoms into compounds.
• B. The movement of electrons from cations to anions.
• C. The mutual attraction of opposite electrical charges.
• D. The sharing of electrons.

Answer: (C)

Verified step by step guidance

1. Begin by understanding the nature of ionic bonds. Ionic bonds are formed between two atoms when one atom donates an electron to another, resulting in the formation of ions.
2. Recognize that ions are charged particles. A cation is a positively charged ion, while an anion is a negatively charged ion.
3. Consider the principle of electrostatic attraction. Ionic bonds are primarily formed due to the electrostatic attraction between oppositely charged ions, i.e., cations and anions.
4. Reflect on the fact that this mutual attraction between opposite charges is what holds the ions together in an ionic compound, giving the bond its strength.
5. Understand that while electron transfer is involved in the formation of ions, the strength of the ionic bond itself is due to the attraction between the resulting charged ions, not the movement or sharing of electrons.
