This week, flowers, fibre optics and the element that can't quite make up its mind whether it's a metal or not. Concerning the electronic attributes, it is a half-metal and thusly useful in many electronic applications as a semiconductor. Germanium is a chemical element with symbol Ge and atomic number 32, that’s used as a semiconductor in transistors and diodes, popping up in a few classic effects like the early period Arbiter Fuzz Face, the storied Dallas Rangemaster and the Maestro Fuzz-Tone. The percentage of a commodity which is recycled. Germanium is found in argyrodite (a sulfide of germanium and silver), in germanite (composed of about 8% of the element), in coal, in zinc ores, and other minerals. Germanium is an element critical in the construction of Kearny Fuchida drives and is an expensive and rare commodity. Germanium is a mineral found in the soil, in foods and many healing herbs such as Aloe Vera, garlic and ginseng. Atomic radius, non-bonded
