Seth is making a slideshow about precious metals for a school project. He learns that gold (Au), silver (Ag), and copper (Cu) are often used in jewelry and coins. Seth also learns that they are all transition metals. He wants to explain the properties of these metals to his classmates. Which statement should Seth include in his slideshow?

This question is incomplete without the presence of options which are below

A. These metals have very low melting points.

B. Gold, silver, and copper are highly reactive.

C. These metals resist heat and are less reactive than group 1 and 2 metals.

D. Gold, silver, and copper have very different physical and chemical properties.

The correct option is C

Explanation:

Generally in the periodic table, transition metals (found in the d-block in the periodic table) are less reactive than the alkali metals (group 1 elements) and alkali earth metals (group 2 elements). Hence, they resist heat and thus corrosion. They also have high melting points. It is for these reasons gold, silver and copper and copper are comfortably used in jewelry and coin.

Using highly reactive metals in jewelry and coin will make them react with sweat or rain when the person is beaten by the rain. And could even cause a potential skin/body hazard when worn in a highly heated environment like the kitchen.
