The chemical element of atomic number 48, a silvery-white metal,
  1. The chemical element of atomic number 48, a silvery-white metal

  1. a soft bluish-white ductile malleable toxic bivalent metallic element; occurs in association with zinc ores
  2. Cadmium is a chemical element with the symbol Cd and atomic number 48. The soft, bluish-white metal is chemically similar to the two other metals in group 12, zinc and mercury. ...
  3. a metallic chemical element (symbol Cd) with an atomic number of 48
  4. (Cadmiums) Brilliant permanent pigments which are suitable for most techniques. Cadmiums turn black when mixed with copper colors, such as emerald green and brown when mixed with lime.. The colors include cadmium yellow, green and red. The latter is considered the best substitute for vermilion.
  5. (Cadmiums) A metal found in several compounds: cadmium oxide, cadmium carbonate, cadmium chloride, cadmium sulfate, and cadmium sulfide. In paints, inks, enamels, glazes, and dyes, and permanent pigments are prepared from cadmiums, mostly cadmium sulfate. Cadmiums are toxic.
  6. A chemical element used in making certain types of solar cells and batteries.
  7. A metallic element highly resistant to corrosion, used as a protective plating on certain parts and fittings.
  8. A transition metal in Group 12 of the periodic table – symbol Cd, atomic number 48.
  9. A ductile metal which may be used in the production of new batteries.
  10. A heavy metal used primarily for metal plating and coating operations, in applications such as transportation equipment, machinery and baking enamels, photography, and television phosphors. It also is used in nickel-cadmium and solar batteries, and in pigments. ...
  11. Symbol:"Cd" Atomic Number:"48" Atomic Mass: 112.41amu. Cadmium is one of the transition elements. This bluish metal is actually very soft and can be cut with a knife. You will find it used in nickel-cadmium batteries, nuclear reactors, and as a pigment. It is toxic. ...
  12. (in  cadmium (Cd) (chemical element): Properties, occurrence, and uses)
  13. is present in trace concentrations in fresh water as a result of natural weathering processes. Concentrations above about 0.01 mg/L can usually be attributed to human activities such as mining, agriculture and the burning of fossil fuels. Concentrations above this level may be toxic to aquatic life.
  14. [cadmio] a naturally occurring carcinogenic toxic heavy metal usually associated with waste motor oil (produced as a result of use in a motor containing cadmium alloyed metals)
  15. A small percentage is derived from drinking water.  It can be present as an impurity in galvanized pipes, solders used in fitting water heaters and coolers, or polyethylene pipes, and, as such, may contaminate water supplies through distribution.
  16. The MCL for cadmium is 0.01 mg/L. Cadmium poisoning is associated with kidney disease and hypertension and possibly mutations. For freshwater the concentration should be less than 0.0004 mg/L.
  17. A metallic element that occurs naturally in tiny amounts in air, water, soil, and food. It is a byproduct of zinc refining, and is used to make batteries, pigments, plastics, alloys and electroplate. It is also found in cigarette smoke. ...
  18. A "transition metal", with the periodic symbol Cd. This metal is relatively rare and is toxic. It is widely used in batteries, although its use is slowly being phased out.
  19. A toxic heavy metal to which the most stringent discharge standards apply; a prescribed red list compound with an environmental quality standard (EQS) of 5 -g/l.
  20. Inhalation affects respiratory system and kidneys. Carcinogenic. Teratogenic. Used in some artist's oil colours.
  21. A metal used in about the shape of a pencil for obtaining voltage of positive or negative plates. It is dipped in the electrolyte but not allowed to come in contact with plates.
  22. ACCU-Tread base coverstock material plus exclusive Storm particle. The particles add extra friction between the ball and the lane.
  23. An element that has atomic number 48. It is often used as a plating metal because it possesses superior corrosion resistance (compared to zinc) and high lubricity which lowers the frictional coefficient of the surface. Highly toxic; restricted under the RoHS directive. (top)
  24. Low levels are found in all foods. Largest dietary contributors are grains and cereal products. Highest levels are found in leafy vegetables, potatoes, and other root crops. Long-term exposure to low levels may cause kidney disease, cancer, lung damage, and fragile bones.
  25. A metal that is used as an alloy in gold solders to promote easy flowing under heat.
