Non-metals usually form _________________ oxides?
Correct answer: A. Acidic
- A. Acidic
- B. Amphoteric
- C. Neutral
- D. All of the above
Explanation
Non-metal oxides are usually acidic because they react with water to form acids or with bases to form salts, as SO3 forms H2SO4. The likely mistake is choosing all of the above because some non-metal oxides are neutral, such as CO and NO, but the usual classification is acidic.

About Reactions of Group IV Elements
Group IV, or Group 14, chemistry covers the trends from carbon and silicon to tin and lead, including their reactions with oxygen, halogens, water, acids and alkalis. It also examines the structures and properties of their oxides and chlorides, oxidation states, and the inert pair effect, rather than treating all members as equally metallic.
