Amphoteric oxides are those, which possess--- properties.
Correct answer: C. Acidic and basic
- A. Acidic
- B. Basic
- C. Acidic and basic
- D. Neutral and acidic
Explanation
Amphoteric oxides are unique because they can exhibit both acidic and basic properties under different conditions. They react with both acids and bases, acting as an acid when reacting with bases and a base when reacting with acids. Examples of amphoteric oxides include aluminum oxide (Al₂O₃) and zinc oxide (ZnO).

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
