This hasn't took place simply because there remain applications where germanium is efficacious, specially from the specialist electronics of night time eyesight products and as being a element with silica from the fibre in the fibre optic cables Employed in communications.

Germanium and many of its pure compound are non-harmful as They're insoluble in water. selected artificial salts of germanium are poisonous and have shown to obtain harming results on kidneys. Germanium will not be a biologically considerable component and have no purpose while in the bodies of plants or animals.
Shiny and silvery, nevertheless quite brittle, germanium is an important component in semiconductors and fiber optics. A number of people Imagine germanium supplements have overall health Positive aspects, but analysis hasn't supported All those promises.
As a consequence of Mendeleev's prediction of ekasilicon, germanium's location around the periodic desk was confirmed because of the comparable Houses predicted and very similar properties deduced from examining the mineral.
Germanium's existence was predicted right before any individual isolated it. This was a triumph for Dmitri Mendeleev in his development from the periodic table. By 1869, Mendeleev experienced assembled a crude desk in the known factors, arranging them In line with their chemical Houses and atomic weights.
