copper

Copper is an element having Cu as its symbol. Its atomic number is 29. This ductile metal is a very good conductor of heat and energy. Malleability and softness characterize pure copper. On scratching its surface, you will find its original color, reddish-orange. It is largely used for making electrical cables because of its electrical conductivity and in other equipments and for producing a number of metallic alloys.

Chemical Formula/Atomic number
Cu

Derivation of Name
Copper and its alloys are in use for generations. In the Roman period, copper was mainly mined in Cyprus and thus the metal was originally named “сyprium” because of its origin, and then edited to Cuprum.

Occurrence
Copper is there in the Earth's outer layer with a concentration of nearly 50 parts per million (ppm), wherein it occurs as native copper ore or in minerals like Copper Sulfides like, Chalcocite and Chalcopyrite, and as copper carbonates like Azurite and Malachite, and also as a copper oxide mineral like Cuprite.

Gemology

copper

Copper metal channels energy. When used in association with another mineral, it increases the energy of that stone. For making a potent tool, it is recommended to wrap copper wire around a crystal wand. The most powerful tool is made by filling a copper pipe with stones and on each end, fitting a crystal point. (Size: 3/4" x 1/2")

Source
Copper in the elemental form was found out in huge quantities that weighed about 420 tonnes in the year 1857 in Michigan on the Keweenaw Peninsula of US. The local copper discovered was in the form of a polycrystals, having the biggest lone crystal of size 4.4 x 3.2 x 3.2 cm.

Mineralogy
All living beings essentially have traces of copper as it is the main component of the enzyme Cytochrome Oxidase of the respiratory enzyme complex. In crustacean, and mollusks, copper is a component of a blood pigment hemocyanin, which is substituted by the hemoglobin in fish and other vertebrates. The hemoglobin is an iron-complex. The main parts of the human body containing copper are bones, muscles and liver. Copper compounds are used as fungicides, bacteriostatic materials and preservatives meant for wood.

Color
It occurs in a red-orange color with metallic luster.

Density
