Why is Germanium important?
(The name germanium derives from the Latin word Germania [Germany] and was given to the element by Winkler.) Many other substances now also are used as semiconductors, but germanium remains of primary importance in the manufacture of transistors and of components for devices such as rectifiers and photocells.
What are 3 uses for germanium?
The largest use of germanium is in the semiconductor industry. When doped with small amounts of arsenic, gallium, indium, antimony or phosphorus, germanium is used to make transistors for use in electronic devices. Germanium is also used to create alloys and as a phosphor in fluorescent lamps.

What is germanium and its uses?
Uses and properties A silvery-white semi-metal. It is brittle. Germanium is a semiconductor. The pure element was commonly doped with arsenic, gallium or other elements and used as a transistor in thousands of electronic applications.
Is GE a metal or nonmetal?
We know germanium isn’t a flower, but it’s slightly harder to say just what it is. Most elements are either metals or nonmetals. Germanium falls in the same group as carbon and silicon, but also as tin and lead. Germanium itself is classified as a metalloid.
Are TA OS RH metal or metalloid?
Tantalum (Ta), Osmium (Os) and Rhodium (Rh) are metals. Explanation: Metals are good conductors of heat and electricity and they can be hammered into sheets (malleable).
What does RH stand for on the periodic table?
Rhodium
Is fluorine a metal?
Fluorine (F) is the first element in the Halogen group (group 17) in the periodic table. It is the most electronegative element, given that it is the top element in the Halogen Group, and therefore is very reactive. It is a nonmetal, and is one of the few elements that can form diatomic molecules (F2).
What are pure metals?
Pure metals are those metals that have not been alloyed with other metallic elements; commercially pure metals are 99% pure minimum. Pure metals are those metals that have not been alloyed with other metallic elements; commercially pure metals are 99% pure minimum.
