Which of the following period four metals is the most likely to be found in the electrical wiring in many homes? (A) Cobalt, (B) copper, (C) manganese, (D) nickel, or (E) scandium.

In this question, we need to identify the period four element used in electrical wiring.

Let us first discuss scandium. This element is a metal with high mechanical strength, high ductility, and properties related to corrosion resistance. Manufacturers use scandium to make alloys for aerospace industry components and sports equipment, such as bicycle frames.

The next period four metal we will discuss is manganese. People use this element for making alkaline batteries, fertilizers, and antiseptics. Some manganese compounds also make effective catalysts and speed up chemical reaction processes.

We can now consider the period four metal cobalt. Several cobalt compounds have vivid and aesthetically pleasing colors. People have used cobalt compounds for centuries to give glass and ceramics a rich blue color. People currently use cobalt for diagnosing cancer and as a catalyst in chemical industrial processes. They also use the metal for food irradiation purposes.

Nickel is on the right side of cobalt in period four of the periodic table of elements. Nickel is a component of lots of rechargeable batteries and a catalyst in some industrial chemical reactions. Lots of countries used to make coins with nickel, but this is much less common now.

Finally, we can consider the last listed period four metal. Copper not only has corrosion resistance properties, but it is also a primary component of the alloy bronze. It has electrical conductivity properties, and countless manufacturers use the metal for electrical wiring.

Therefore, of the period four metals listed, the most likely to be found in the electrical wiring in many homes is (B) copper.
