I am Element!
Hi! I am Germanium, a metalloid. Here is a little about me. Try not to confuse me with Tin because we're are chemically the same.
My Compounds
(My Friends!)
-germanium (IV) hydride
-germanium (III) hydride
- (below) germanium (II) iodide
Crystal structure of germanium (II) iodide
and many others!!

My Story: In 1871, I was one of the elements that Dimitri Mendellev predicted to exist as a missing analogue of the silicon group (he called us “ekasilicong”). The existence of me was proven by Clemens Winkler in 1886 (thank goodness for him!). Making the discovery of me an important confirmation of Mendeleev’s idea of element periodicity.

My Jobs I work as a
  • Chemotherapy
  • Electronics/solar electrical applications
  • Fiber-optic systems
  • Infrared optics
  • Metallurgy
  • Phosphors
  • Polymerization catalysts
  • also as a tv picture tube
