cadmium it's Cd, mix it with nickle to make a rechargeable battery, it's mostly found with zinc, it's poison to humans doesnt that stink.

 

 

Physical Properties

It is a soft metal. It can be cut with a knife that’s how soft it is. It is a white metal and it conducts electricity well because it’s a metal. It’s physical appearance is almost just like zinc just above it an the periodic table.

History

Friedrich Stromeyer a German scientist first discovered cadmium in 1817. He discovered it when he was researching zinc carbonate and he found an impurity in a peace and when that peace was heated it changed colors but when the other peaces were heated they did not change color. He extracted parts of the impurities and discovered it was a different element which he named cadmium.

 
 

Mining

To get cadmium it is usually taken from zinc ores and is never found uncombined in nature. It can also be extracted form lead, mercury and copper. So they are mined and cadmium is extracted from those elements. Cadmium cold also be mined by it’s self but it would cost more to mine than what they could sell it for.

Toxic

It is very dangerous to the human body. If it is eaten or gets into your blood stream it is very difficult to get out because it dissolves in water and most other liquids. It attacks the kidney, respiratory system and cause bone disease.

Uses

Cadmium can be mixed with nickel to make rechargeable batteries that are used every day. That’s its most practical use but Cadmium may be used as a coating on metals like iron or steel, where it makes a chemical resistant coating. People use cadmium salts are used in photography and in the making fireworks, rubber, fluorescent paints and glass. Cadmium has been used as a control or shielding material in atomic energy plants because it can absorbent low-energy neutrons very well. Cadmium lowers the melting point of all the metals that it gets alloyed with. It is mixed with lead, tin, and bismuth to make an automatic sprinkler systems, fire alarms, and electric fuses.
