Definition of the Indium Element
A soft, malleable, silvery-white metallic element found primarily in ores of zinc and tin, used as a plating over silver in making mirrors, in plating aircraft bearings, and in compounds for making transistors.

Origin / Meaning of the name Indium
The name originates from the color Indigo in its atomic spectrum.

Classification of the Indium Element
Indium is classified in the 'Other Metals' section which can be located in groups 13, 14, and 15 of the Periodic Table. All of these elements are solid, have a relatively high density and are opaque.

Facts about the Discovery & History of the Indium Element
Indium was discovered by Ferdinand Reich and Theodor Richter in Germany in 1863. Richter  isolated the metal in 1867.

Occurrence the Indium Element
From residues generated during zinc ore processing / refining
Found in iron, lead, and copper ores
Canada is the leading producer

Associated Uses of Indium
Coating of high-speed bearings
Indium-tin-oxide thin films for liquid crystal displays (LCD)
Making mirrors
Making transistors
Photoconductors

Indium - IUPAC and the Modern Standardised Periodic Table
The Standardised Periodic Table in use today was agreed by the International Union of Pure Applied Chemistry, IUPAC, in 1985 and now recognises more periods and elements than Dimitri  Mendeleev knew in his day but still all fitting into his concept of  the "Periodic Table" in which Indium is just one element that can be found.
