Final answer:
The action of a balloon filled with radon gas falling to the floor when released is a physical property. This is determined by the density of Radon gas. In contrast, radiation emission from radon would be considered a chemical property as it involves a nuclear transformation.
Step-by-step explanation:
The property of a balloon filled with radon gas falling to the floor when released can be classified as a physical property. This is because the falling of the balloon is based on the density of the radon gas, which is about eight times more dense than air. A change in physical property does not alter the nature of the substance and the radon gas is still radon gas before and after the balloon falls. In a chemical property, the substance would have to undergo a chemical reaction and form a new substance, which isn't the case here.
Radiation emission from radon gas would be a chemical property as it involves nuclear transformation, changing the nature of radon, but this isn't happening with the balloon falling. This exercise demonstrates the importance of understanding the difference between physical and chemical properties in Chemistry in everyday life.
