Germanium Element in Periodic Table | Atomic Number Atomic Mass

Germanium

Germanium Element:

Germanium is the chemical element and it is a member of group 14 and period 4 in the periodic table. Atomic number of silicon is 32 and is indicated by the symbol Ge. Germanium is a lustrous, hard, greyish- white a metalloid. Germanium's abundance in the Earth's crust is approximately 1.6 ppm.  Germanium contains 5 natural isotopes and also 19 artificial isotopes created in laboratory. Natural isotopes are 74Ge, 72Ge, 73Ge, 79Ge, 76Ge.

Germanium Element Uses:

  • The most common use of germanium is as a semiconductor. And it is also used  in  thousands of electronic applications.
  • Germanium oxide has a high index of refraction and dispersion. This makes it especially useful for wide-angle camera lenses and objective lenses for microscopes.
  • It is used as an alloying agent and as a catalyst.
  • It is also used infrared spectroscopes
