Periodic table provides a basic framework to study elements with respect to their__________________?
Correct answer: D. All
- A. Physical properties
- B. Chemical properties
- C. Properties of their compounds
- D. All
Explanation
The periodic table arranges elements so that their physical properties, chemical properties, and the properties of their compounds can be studied systematically. Option b is a tempting choice because chemical properties are central, but the table provides a broader framework covering all three areas.

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.
