Germanium was an element whose existence was predicted by Mendeleev in 1871. He predicted that the then unknown element germanium should resemble silicon in its properties. He suggested therefore the name ekasilicon (symbol Es). His predictions for the properties of germanium are remarkably close to the reality. Germanium was discovered in a mineral called argyrodite by Clemens Alexander Winkler in 1886. In the summer of 1885, a rich silver ore of unusual appearance was found at Himmelsfurst Fundgrube near Freiburg. Germanium is found within the confines of our Earth's atmosphere as either a gas that never changes or as a solid or as a liquid. the state it is found in merely depends where within said confines you find Germanium at the particular time.
