Definition of the Germanium Element
A brittle, crystalline, gray-white metalloid element, widely used as a semiconductor, as an alloying agent and catalyst, and in certain optical glasses..

Origin / Meaning of the name Germanium
The name originates from the the Latin word Germania meaning 'Germany'

Classification of the Germanium Element
Germanium is classified as a "Metalloid" element and is located in Groups 13, 14,15, 16 and 17 of the Periodic Table. An element classified as a Metalloid has properties of both metals and non-metals. Some are semi-conductors and can carry an electrical charge making them useful in calculators and computers.

Facts about the Discovery and History of the Germanium Element
Germanium was discovered by Clemens Winkler in Germany in 1886. Mendeleev called it "ekasilicon"

Occurrence the Germanium Element
Found in argyrodite (sulfide of germanium and silver), coal; germanite and zinc ores

Associated Uses of Germanium
Electric guitar amplifiers
Semi-conductor
An alloying agent
Infra-red spectroscopes and optical equipment
Camera and microscope lenses
Medical

Germanium - 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 Germanium is just one element that can be found.
