What is the origin of name of germanium?
(The name germanium derives from the Latin word Germania [Germany] and was given to the element by Winkler.)
How was germanium used in the past?
Germanium played an essential role in the development of the first transistor and its usefulness as a semiconductor thus became recognized. In the late 1950s, interest grew in using silicon instead of germanium because of its larger bandgap and the existence of stable silicon oxides.
When and how was germanium discovered?
History and Uses: First proposed to exist by Dmitri Mendeleyev in 1871 based on gaps in his newly created Periodic Table of Elements, germanium was discovered by the German chemist Clemens Winkler in the mineral argyrodite (Ag8GeS6) in 1886.
What is the importance of germanium?
Germanium is stable in air and water, and is unaffected by alkalis and acids, except nitric acid. Germanium is an important semiconductor, mainly used in transistors and integrated circuits. They are often made from germanium to which small amounts of arsenic, gallium, or other metals. Germanium forms many compounds.
When was germanium found?
1886
Who invented germanium?
Clemens Winkler
What is the color of arsenic?
silver-gray
What elements does germanium react with?
The surface of lumps of germanium is protected by a very thin layer of germanium dioxide, GeO2. It is more reactive than silicon, which is immediately above germanium in the periodic table, but not by much. At red heat, germanium reacts with oxygen in air to from germanium dioxide.
Why germanium is called a metalloid?
1. Germanium is shiny like metals but brittle like non-metal. It shows some of the properties like metal and some like non-metals. Most important it behaves as semi-conductor like Silicon hence like silicon it is considered as metalloid.
What gas is germanium found in?
Germanium is located in the middle of the carbon family, which is Group 14 (IVA) in the periodic table. The periodic table is a chart that shows how chemical elements are related to each other. Carbon and silicon are above germanium and tin and lead are below it.
