Chapter 2.1, Problem 1PP

Interpretation Introduction

Interpretation: Whether the cube at the right side is pure aluminum or not needs to be determined.

Concept introduction: 3-dimensional structure (square) with 6 equal sides is identified as a cube. An element that effortlessly forms positive (+ve) ions (or cations) is defined as a metal. Metals have metallic bonds.

Answer to Problem 1PP

No, the cube pictured at right is not made of pure aluminum.

Explanation of Solution

The given cube is as follows:

Aluminum is usually listed in the class of metal. The color of aluminum is silvery-white and also, it is a light weight metal.

Pure aluminum is ductile, soft, corrosion-resistant. It has a quality of high electrical conductivity. The density of the cube (pictured) is not equal to the density of pure aluminum (it is $2.7{\text{ g/cm}}^{\text{3}}$ ). So, the cube pictured at right is not made of pure aluminum.

Conclusion

The cube pictured at right is not made of pure aluminum.
