History of Germanium

Germanium was predicted by Russian chemist Dmitri Mendeleev in 1869 after he developed the periodic table of elements. He predicted the element because he noticed a gap between silicon and tin. As a result, he theorized that there were several elements yet to be discovered, including element number 32 (Germanium). When he first figured it out, he initially called it eka-silicon.

His prediction turned out to be pretty accurate. He predicted that the element that would eventually become Germanium would have a density of 5.5 grams per cubic centimeter and atomic weight of 70. The actual numbers are 5.323 grams per cubic centimeter and an atomic weight of 72.630. As a result of his accuracy with Germanium, the periodic table was given credibility.

The element was officially discovered by Clemens A. Winkler in 1886 in Germany. The discovery was made in a mineral sample from a silver mine. The name he gave it, Germanium, comes from the Latin ‘Germania’ meaning Germany.
