At least it would do if it didn't explode as soon as it came into contact with water. Copper sulfate is widely used as an agricultural poison and as an algicide in water purification. Copper, silver, and gold are in group 11 of the periodic table; these three metals have one s-orbital electron on top of a filled d-electron shell and are characterized by high ductility, and electrical and thermal conductivity. Copper has been used by humans for as many as ten thousand years. Copper, symbol Cu, has a Face Centered Cubic structure and Copper color. Copper has been known since ancient times. You're listening to Chemistry in its element brought to you by. Unlike mammals, which use iron (in haemoglobin) to transport oxygen around their bodies, some crustaceans use copper complexes. We welcome your feedback. High-purity copper (99.999+ %) is available commercially. This is probably why it is commonly used as a pesticide, fungicide and algaecide, because such small amounts can get the jobs done.

An integrated supply risk index from 1 (very low risk) to 10 (very high risk). Copper metal does occur naturally, but by far the greatest source is in minerals such as chalcopyrite and bornite. This is approximately the sum of the number of protons and neutrons in the nucleus. They easily could because it's an excellent heat conductor as well, but I find this metal so interesting for many other reasons as well. Greenockite (CdS) is the only mineral of any consequence bearing cadmium. All US coins are now copper alloys, and gun metals also contain copper. The percentage of a commodity which is recycled.
