Chapter 9 Synopsis
Cadmium, also known as element 48, is located in period five and group ten of the transition metals (12 if you go straight across) on the periodic table. It's electron configuration is 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10. It was discovered by Friedrich Stromyer in 1817 and was named after the Greek word for zinc ore. Cadmium is never found by itself naturally. It is closely related to and often found with zinc. For this reason most zinc ores contain some amount of cadmium, but ores containing zinc sulfide have the highest amount of cadmium. There are three cadmium minerals: greenockite, hawleyite, and otavite. (Butterman and Plachy, 2002). One example of where to find cadmium would be the Broken Hill mine in Australia (Australia Mines Atlas). Cadmium is an important element because it is related to zinc meaning they have some similarities in properties that allow cadmium to be used in different products such as certain types of batteries, pigments, and stabilizers for plastics (Butterman and Plachy, 2002). Another reason Cadmium is important is that this element is highly poisonous meaning it has to be used cautiously. One of the special characteristics of this element is that it, once consumed, does not leave the body, but instead replaces the zinc in the body (Ch9, 154).
