It is less abundant than either tin or lead. Overview of Germanium The atomic number of an element never changes, meaning that the number of protons in the nucleus of every atom in an element is always the same. This is not to be confused with the relative percentage isotope abundances which totals 100% for all the naturally occurring isotopes. Classified as a metalloid, Germanium is a solid at room temperature. Germanium Basic Facts . Isotopes differ from each other according to their mass number. Germanium is a lustrous hard metalloid element, belongs to group 14 of the periodic table. Germanium fluoride (GeF 2) Germanium dioxide (GeO 2) Germanium hydride (Ge 2 H 6) Germanium tetrachloride (GeCl 4) Interesting facts: In its natural state it is brittle and crystalline. Element Germanium (Ge), Group 14, Atomic Number 32, p-block, Mass 72.630. ››More information on molar mass and molecular weight. Germanium is a chemical element with Ge as its symbol. of protons = mass number. = 32. therefore, the no. There are five naturally occurring isotopes of germanium: germanium-70, germanium-72, germanium-73, germanium-74, and germanium-76. At room temperature (300 K), for Ge (Si) per cm 3 . Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images. : Number of neutrons + no. Of these, 76 Ge is very slightly radioactive, decaying by double beta decay with a half-life of 1.78 × 10 21 years (130 billion times the age of the universe). Germanium Page One. Just the facts. Germanium was first located in a rare mineral called argyrodite. Thus, at room temperature in Ge (Si), one atom out of about 10 9 (10 12 ) contributes one electron-hole pair through breaking of covalent bond. Isotopes are two or more forms of an element. Germanium Menu. Stable 74 Ge is the most common isotope, having a natural abundance of approximately 36%. Atomic number (number of protons in the nucleus): 32; Atomic symbol (on the periodic table of elements): Ge In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all … Its ores are rare. All atoms have a mass number which is derived as follows. It belongs to group 14 of the periodic table and its atomic number is 32. SO; in your question we have: mass no. It is a gray-white metalloid. = 70. atomic no. It forms a large number of organometallic compounds. It is also a flammable gas (2.1). Other compounds include: Germanium dichloride Ge Cl 2, Germanium dioxide GeO 2, Germanium tetrachloride GeCl 4 this is very irritating to eyes and membranes. In the above, the most intense ion is set to 100% since this corresponds best to the output from a mass spectrometer. Germanium (32 Ge) has five naturally occurring isotopes, 70 Ge, 72 Ge, 73 Ge, 74 Ge, and 76 Ge. Germanium is a chemical element with symbol Ge and atomic number 32. Germaine is a hazardous substance UN2192 which is classified as a poisonous gas (2.3). It's an element that was predicted by Mendeleev in 1871. Common Uses Predicted by Mendeleev in 1870, germanium was actually found in 1886 by Winkler. Isotope abundances of germanium. The number of atoms/cm 2 in Ge or Si is of the the order of 10 22. In pure form, the element is a grayish-white … Atomic Number: 32 Symbol: Ge Atomic Weight: 72.61; Discovery: Clemens Winkler 1886 (Germany) Electron Configuration: [Ar] 4s 2 3d 10 4p 2; Word Origin: Latin Germania: Germany Properties: Germanium has a melting point of 937.4 C, boiling point of 2830 C, specific gravity of 5.323 (25 C), with valences of 2 and 4.
