1. Cadmium

   Cadmium is a chemical element with the symbol Cd and atomic number 48. This soft, silvery-white metal is chemically similar to the two other stable metals in group 12, zinc and mercury. Like zinc, it demonstrates oxidation state +2 in most of its compounds, and like mercury, it has a lower melting point than the transition metals in groups 3 through 11. Cadmium and its congeners in group 12 are often not considered transition metals, in that they do not have partly filled d or f electron shells in the elemental or common oxidation states. The average concentration of cadmium in Earth's crust is between 0.1 and 0.5 parts per million (ppm). It was discovered in 1817 simultaneously by Stromeyer and Hermann, both in Germany, as an impurity in zinc carbonate. Cadmium occurs as a minor component in most zinc ores and is a byproduct of zinc production. Cadmium was used for a long time as a corrosion-resistant plating on steel, and cadmium compounds are used as red, orange and yellow pigments, to color glass, and to stabilize plastic. Cadmium use is generally decreasing because it is toxic (it is specifically listed in the European Restriction of Hazardous Substances Directive) and nickel-cadmium batteries have been replaced with nickel-metal hydride and lithium-ion batteries. One of its few new uses is in cadmium telluride solar panels. Although cadmium has no known biological function in higher organisms, a cadmium-dependent carbonic anhydrase has been found in marine diatoms.

1. cadmium

   Cadmium is a chemical element with the symbol Cd and atomic number 48. It is a soft, bluish-white metal that is rarely found in nature and is usually obtained as a byproduct of zinc, lead, and copper refining. Cadmium is used mainly in batteries, coatings, pigments, and as a stabilizer for plastics. It is known for its toxic effects on human's health and the environment.

   Cadmium is a chemical element with the symbol Cd and atomic number 48. This soft, bluish-white metal is chemically similar to the two other stable metals in group 12, zinc and mercury. Like zinc, it prefers oxidation state +2 in most of its compounds and like mercury it shows a low melting point compared to transition metals. Cadmium and its congeners are not always considered transition metals, in that they do not have partly filled d or f electron shells in the elemental or common oxidation states. The average concentration of cadmium in the Earth's crust is between 0.1 and 0.5 parts per million. It was discovered in 1817 simultaneously by Stromeyer and Hermann, both in Germany, as an impurity in zinc carbonate. Cadmium occurs as a minor component in most zinc ores and therefore is a byproduct of zinc production. It was used for a long time as a pigment and for corrosion resistant plating on steel while cadmium compounds were used to stabilize plastic. With the exception of its use in nickel–cadmium batteries and cadmium telluride solar panels, the use of cadmium is generally decreasing. These declines have been due to competing technologies, cadmium’s toxicity in certain forms and concentration and resulting regulations. Although cadmium has no known biological function in higher organisms, a cadmium-dependent carbonic anhydrase has been found in marine diatoms.

Examples of cadmium in a Sentence

1. Anna Callan:

   Because cadmium is present in so many food types, there is no simple way to reduce dietary exposure, the best advice is to follow a balanced and varied diet and to eat low-fat dairy foods as a source of calcium to help build strong bones.

2. Jane Houlihan:

   There's also not as much evidence that cadmium is neurotoxic to babies, or at least the body of evidence isn't there at the same levels as lead and arsenic, lead and arsenic damage isn't reversible -- these are permanent impacts on IQ, learning ability and behavior, so it's a big deal.

3. John Nelson:

   I started going down to the burn pit because I was growing more and more concerned with the amount of debris, so I started taking a look and I started seeing batteries, the cadmium batteries, the lead. All of that was burning. They were putting the oils and the paints and fuels. All of this stuff, and it was leading to this creation of toxicity and I was becoming concerned about it. john Nelson would wait until the middle of the night to drop it off.
