XYZ are the elements in the same short period of the periodic table the oxide of X is amphoteric the Exide of Y is basic and the Exide of Z is acidic what is the order of increasing atomic number for these elements?
Correct answer: C. YXZ
- A. XYZ
- B. XZY
- C. YXZ
- D. ZXY
Explanation
In a given period of the periodic table, the nature of oxides changes from basic to amphoteric to acidic as you move from left to right. This corresponds to increasing atomic numbers. Therefore, the correct order of increasing atomic number for these elements is Y (basic oxide), X (amphoteric oxide), Z (acidic oxide), making the sequence YXZ. Option C is correct. The other options do not follow this trend, thereby making them incorrect.

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.
