Shiny and silvery, yet very brittle, germanium is an important component in semiconductors and fiber optics. Some people think germanium supplements have health benefits, but research has not supported those claims. The existence of germanium was predicted by Russian chemist Dmitri Mendeleev in , after he developed the periodic table of elements, according to Chemistry Explained. Arranging the elements by atomic weight left some gaps in the table. Mendeleev theorized that there were several elements yet to be discovered, including element No. In , Clemens Winkler, a German chemist, discovered what was then referred to as "eka-silicon" in an ore known as argyrodite. The ore contained silver, sulfur, iron oxide, and zinc with about 7 percent of the unknown metal. According to Chemistry Explained, Mendeleev had predicted that element 32 would have a density of 5. The accuracy of Mendeleev's prediction increased chemists' confidence in the periodic table.

Germanyum faydaları

Germanium, categorized as a metalloid in group 14, the carbon family, has five naturally occurring isotopes. Germanium, abundant in the Earth's crust, has been said to improve the immune system of cancer patients. It is also used in transistors, but its most important use is in fiber-optic systems and infrared optics. The metalloid was one of the elements predicted by Mendeleev in ekasilicon to fill out his periodic table and was discovered in by Winkler. In a mine near Freiberg, Saxony, a new mineral was found in First the mineral was called argyrodite, but later, when Clemens Winkler examined this mineral he discovered that it was similar to antimony. At first he wanted to name it neptunium, but because this name was already taken he named it germanium in honor of his fatherland Germany. The position of where germanium should be placed on the periodic table was under discussion during the time due to its similarities to arsenic and antimony.
