** -There is much history on our element. First, Indium was discovered by Reich and Richter who later isolated the metal. **  ** -Named for the word //indium//, for the Latin word //indigo.// -When heated past its melting point it burns and emits a violet flame.  -Until 1924, a gram or so constituted the world's supply of this element in isolated form. - It is probably about as abundant as silver. -About four million troy ounces of indium are now produced annually in the free world. Element Uses -4 Million ounces produced  -Soil is rich in Indium -No biological role -Indium compounds are highly toxic -Indium compounds damage the heart, kidney, and liver, and may be teratogenic. -Environmental effects from the sunstane have not been investigated. -used to make low-melting alloys, alloyed with gallium -it can be plated onto metal and evaporated onto glass, forming a mirror as good as those made with silver, but with more resistance to atmospheric corrosion -photocells **
