Pure germanium is a hard, lustrous, gray-white, brittle metalloid. It has a diamondlike crystalline structure and it is similar in chemical and physical properties to silicon. Germanium is stable in air and water, and is unaffected by alkalis and acids, except nitric acid. Therefore it’s a pure substance..
What is the chemical symbol of germanium?
Ge
Is germanium a conductor?
Pure silicon and germanium are poor conductors of electricity because their outer electrons are tied up in the covalent bonds of the diamondlike framework. These atoms are larger and hold their electrons less tightly. They are not conductors in the metallic sense of the word, but are semiconductors.
Who named germanium?
In 1886, Clemens Winkler discovered a rare mineral called argyrodite which contained silver, sulphur and an unknown element, which Winkler named germanium after his home country. 3.
What makes germanium unique?
Germanium is a lustrous, hard, gray-white semi-metallic element with a crystalline and brittle structure. It is a semiconductor. Germanium and the oxide are transparent to infrared radiation. Germanium also has the unusual property that (like water) it expands as it freezes.
Who invented germanium?
Germanium, element #32, was discovered in 1886 by Clemens Winkler. Its first broad application was in the form of point contact Schottky diodes for radar reception during WWII.
What are the advantages of germanium?
Advantages of Germanium Detectors Germanium is preferred due to its atomic number being much higher than silicon and which increases the probability of gamma ray interaction. Germanium has lower average energy necessary to create an electron-hole pair, which is 3.6 eV for silicon and 2.9 eV for germanium.
