Making Money Project

In this paper I will explain the how the characteristics of chromium can make a good coin. By doing so I will be talking about the chemical and physical properties that makes Chromium suitable for coining. I will be comparing another coin's element similarity to my element that I think is suitable for coining. I also considered another element to be a coin and I will be explaining why it wouldn't be of good use as a coin.

Chromium is a gray metallic element that can take on a high polish. Its durability accounts for the fact that more than half the production of chromium goes into metallic products, and about another third is used in refractories. It is also widely used as body trim on automobiles and other vehicles.

Chromium has an atomic weight of 51.996; the element melts at about 1857° C (about 3375° F), boils at about 2672° C (about 4842° F).

Cadmium is a soft, bluish-white metal and is easily cut with a knife. It is similar in many respects to zinc. Cadmium and its compounds are highly toxic. Silver solder, which contains cadmium, should be handled with care. Since it is a metal that can be easily cut I didn't think it would be suitable as a coin. Cadmium melts at 321° C (610° F), boils at 765° C (1409° F). The atomic weight of cadmium is 112.41.

I considered both metals but after comparing the two I would choose Chromium to make a coin rather than Cadmium. Chromium is steel-gray, lustrous, hard, metallic, and takes a high polish. Cadmium is an element that isn't strong enough to be a coin. Chromium also has a...
