Which of the following best describes the main difference between ionic bonds and covalent bonds?

• A. Ionic bonds involve the transfer of electrons from one atom to another, while covalent bonds involve the sharing of electrons between atoms.
• B. Ionic bonds result in the formation of molecules, while covalent bonds result in the formation of crystals.
• C. Ionic bonds occur only between nonmetals, while covalent bonds occur only between metals.
• D. Ionic bonds are weaker than covalent bonds under all conditions.

Answer: (A)

Verified step by step guidance

1. Understand the nature of ionic bonds: Ionic bonds form when one atom transfers one or more electrons to another atom, resulting in positively and negatively charged ions that attract each other.
2. Understand the nature of covalent bonds: Covalent bonds form when two atoms share one or more pairs of electrons to achieve a full outer electron shell.
3. Compare the electron behavior in both bonds: Ionic bonding involves electron transfer leading to ion formation, while covalent bonding involves electron sharing without full transfer.
4. Recognize the typical elements involved: Ionic bonds usually form between metals and nonmetals due to their difference in electronegativity, whereas covalent bonds typically form between nonmetal atoms.
5. Evaluate the given options based on these principles to identify the statement that correctly contrasts ionic and covalent bonds.
