Chapter 18, Problem 5A

To determine

To Explain: Uranium is not dense material even if it is heaviest atom found in nature.

Explanation of Solution

Introduction:

The density is the property of a matter. It is the ratio of mass of the body per unit volume. The density of the matter depends on mass of the individual atoms and the spacing between the atoms.

Uranium has high atomic number and it is the heaviest atom. In Uranium, spacing between the atom is high so it has large volume. As volume is large, it is less dense.

Conclusion:

Due to high volume, Uranium metal is less dense material.
