Cadmium is a shiny metal with a bluish cast (shade) to it. China, South Korea, Canada, Japan, and Kazakhastan led the world in cadmium refinement in the early 21st century. Some chemists don’t regard cadmium as a true transition metal, because it has a full shell of d electrons. As a pigment, cadmium can stay bright even after exposure to sunlight. Calcium in the form of calcium carbonate is used by snails and shellfish to construct shells. Beyond the basics above, what else should we know about nickel? Cadmium is physically similar to zinc but is … In its pure form, cadmium is a silvery white, malleable metal with a bluish hue. An interesting property of cadmium is its effect in alloys. Nickel is a silver-white transition metal with element symbol Ni, a relative atomic mass of 58.69, a density of 8.9g / cm³, a melting point of 1455 ° C, and a boiling point of 2730 ° C.. Nickel has good ductility, magnetic and corrosion resistance. 6 Interesting Facts About Nickel. Most cadmium produced is electroplated onto steel, iron, copper, brass, and other alloys to protect them from corrosion. It is very soft and can almost be scratched with a fingernail. It is found naturally in the earth’s crust and is a relatively rare metal, ranking 67th in abundance among the 90 naturally occurring elements on Earth. Occurrence of the element Cadmium Obtained from zinc refining, mining, smelting. Common Uses of Cadmium Batteries - Nickel Cadmium Pigments Cadmium was discovered in Germany by Fredrich Stromeyer in 1817 . Like mercury below it, cadmium and its compounds are highly toxic. If you could extract all of the calcium from the average adult person, you'd have about 2 pounds (1 kilogram) of the metal. Cadmium pigments help create brilliant yellow, orange, red and maroon pigments in paints and coatings, and are added to plastics to give them color. It is the most abundant metal in the human body, found mainly in bones and teeth. Cadmium plating is especially resistant to attack by alkali. it can act as a barrier to control nuclear fission, about three-quarters of cadmium is used in batteries, the other quarter is mainly used for pigments, stabilizers for plastics eg PVC, it is used in some semiconductors such as cadmium sulfide, cadmium selenide, and cadmium telluride Cadmium is odorless and tasteless, and chemical analysis is most often required to detect its presence. Its melting point is 321 ° C (610 ° F) and its boiling point is 765 ° C(1,410 ° F). What is Cadmium? The density of cadmium is 8.65 grams per cubic centimeter. Cadmium’s chemistry is similar to zinc’s and they are found in the same ores. Artists Henri Matisse and Claude Monet used cadmium pigments to create their well-known works of art, for example. Most cadmium is recovered in one of these three processes. Greenockite is the only cadmium mineral of importance and is nearly always associated with sphalerite. Zinc sits above cadmium in the periodic table. atomic number48 atomic weight112.414 melting point321 °C (610 °F) boiling point765 °C (1,409 °F) specific gravity8.65 at 20 °C (68 °F) oxidation state+2 electron configuration[Kr]4 d 10 5 s 2 … Cadmium (Cd), chemical element, a metal of Group 12 (IIb, or zinc group) of the periodic table. Other facts.. it's carcinogenic.
