Facts about the
Definition of the Element Indium
The Element Indium is defined as...
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.
Interesting Facts
about the Origin and Meaning of the element name Indium
What are the origins of the word Indium ?
The name originates from the color Indigo in its atomic spectrum.
Facts about the
Classification of the Element Indium
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.
Brief Facts about the

Facts and Info about
the element Argon - 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
which includes the Indium element. The famous Russian Scientist,
Dimitri Mendeleev, perceived the correct classification method of
"the periodic table" for the 65 elements which were known in his
time. Indium was discovered by Ferdinand Reich and Theodor Richter
in Germany in 1863. Richter isolated the metal in 1867. The Standardised Periodic Table 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.
