Protons/electrons: 32. So far, Si has been studied the most extensively because of its high specific capacity and cost efficiency; however, Ge is an interesting alternative. The prefix poly- means many, so a polyatomic ion is an ion that contains more than one atom. Currently, the primary source materials for fluorine implant are generally limited to those fluoride gases commonly used on implant tools, such as Boron Trifluoride (BF 3), Silicon Tetrafluoride (SiF 4), or Germanium Tetrafluoride (GeF 4). Elemental silicon, germanium, arsenic, antimony, and tellurium are lustrous, metallic-looking solids. Germanium was one of the elements whose existence was predicted in 1869 by Russian chemist … Lithium-ion batteries using germanium as the anode material are attracting attention because of their high-capacity, higher conductivity, and lithium-ion diffusivity relative to silicon. Use this link for bookmarking this species for future reference. Ionization energy, also called ionization potential, is the energy necessary to remove an electron from the neutral atom. Precipitation., 1992; Staufer, 1980 ). Germanium was first discovered by Clemens Winkler in 1886.654x10^-6 s. Example 3: GeH 4 Similarly in GeH 4, the Germanium (Ge) is bonded to Hydrogen (H). 79.96.
