Copper is a mineral by both the geological and nutritional definitions. A geological mineral is an inorganic substance with a chemical formula and an ordered atomic structure, while a nutritional mineral is a chemical element required by living organisms. Copper falls u...
Copper is in group 11 on the periodic table, along with silver and gold. There is also one other element that theoretically belongs in this group, roentgenium, which has a half life of 26 seconds and has only ever been formed under laboratory conditions.
Copper is a highly conductive, ductile metal. The metal is soft and malleable, although it does possess a great deal of tensile strength. This means that copper is easily formed by hand, but it is not suitable for building structures.
Gold is a mineral and was one of the first used by prehistoric cultures. It is appreciated for its physical appearance, its workability and its ability to withstand chemicals.
Iron is a mineral and a vital nutrient for most animals. Because of its ability to form a bond with oxygen, iron is used by the hemoglobin in red blood cells to transport oxygen from the lungs or gills of an animal to the tissues of its body.
Aluminum is not a mineral. Aluminum is a chemical element with the atomic number 13. It makes up eight percent of the weight of Earth's solid surface and is the third most abundant element, after oxygen and silicon, to be found in Earth's crust.
Minerals are formed under a variety of conditions, including when molten materials cool, when liquids evaporate or cool and under high temperatures and pressures. Minerals are found in the earth's crust and mantle, and many were created when feldspar and quartz reacted ...
