RoseMarie Gallagher and Paul Ingram Solutions for Chapter: The Periodic Table, Exercise 6: Q

Explain why the noble gases are unreactive in nature.

What are the trends in density and boiling points for the noble gases?

Are the trends of density and boiling point trends of noble gases same as that of Group $\mathrm{I}$?

Are the trends of density and boiling point trends of noble gases same as that of Group $\mathrm{VII}$?

The noble gases are widely used. Explain why, and give one use for each.
 

The sixth element in Group 0 is radon (Rn). Would you expect it to be a gas, a liquid, or a solid, at room temperature?

The sixth element in Group $0$ is radon $\left(\mathrm{Rn}\right)$. Would you expect it to be heavier, or lighter, than xenon?

The sixth element in Group $0$ is radon $\left(\mathrm{Rn}\right)$. Would you expect it to be chemically reactive?
