Amphoteric oxide is formed by:
Correct answer: D. Zn
- A. Ca
- B. Fe
- C. Cu
- D. Zn
Explanation
Zn is an amphoteric Oxides of relatively less electropositive elements, such as BeO, Al2O3, Bi2O3 and ZnO are amphoteric and behave as acids towards strong bases and as bases towards strong acids

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.
