Electricity an electronic circuits Germanium is a chemical element with the Symbol(ge) and with the atomic number 32.And are use in electronics,Also they are use in Solar Panels or fluorescent lamps. Silicon is a chemical element with the symbol (si) and with the atomic number 14.Is use for in electronics,to produce silicon waver used in the semiconductor Industry. Silicon was discovered in 1823 The existence of germanium was predicted by Russian chemist Dmitri Mendeleev in 1869 but in 1885, 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. silicon is present in the sun and meteorites. Silicon makes up one quarter of the earth's crust. It is the second most...
