Which property of an element shows the greatest periodic change?
AAtomic radius
BDensity
CBoiling point
DMass number
Answer & Solution
Correct answer: A. Atomic radius
1. Atomic radius shows clear, regular variation along periods and groups.
2. Density and boiling point vary less predictably.
3. Mass number is not periodic at all.
4. So atomic radius is the most clearly periodic property.
