Question

how does a molecular compound compare to the elements that make up the compound? a. the properties of a compound depend on the identity of the component elements, and not the chemical bonds they form. b. the properties of a compound depend on the size of the molecule, and not the component elements. c. the properties of a compound are generally similar to the properties of the elements that make it up. d. the properties of a compound are usually very different from the properties of the elements that make it up.

Explanation:

To determine the correct answer, we analyze each option:

• Option A: Chemical properties of a compound depend on chemical bonds and the elements involved, so this is incorrect.
• Option B: The properties of a compound depend on the elements (and their bonding), not just molecule size, so this is incorrect.
• Option C: A compound's properties are different (not similar) to its constituent elements (e.g., H₂O vs H and O), so this is incorrect.
• Option D: Compounds have unique properties different from their elements (e.g., NaCl vs Na and Cl), so this is correct.

Answer:

D. The properties of a compound are usually very different from the properties of the elements that make it up.
