Chapter 24, Problem 25R

To determine

To complete: the given sentence.

Explanation of Solution

Introduction:

Metals have four definite properties:

1. luster,

2. ductility,

3. malleability, and

4. conductivity.

The property of metal that gives it a glossy or bright appearance due to its ability to reflect light is called luster.

Due to the property of luster, metals such as chromium are used for electroplating to harden other materials and as protection from rust and corrosion. The chromium plating also called chrome forms a highly polished surface that reflects light.

Conclusion: The shiny appearance of metals demonstrates the property of luster.
