››More information on molar mass and molecular weight. In the above, the most intense ion is set to 100% since this corresponds best to the output from a mass spectrometer. : 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). This is not to be confused with the relative percentage isotope abundances which totals 100% for all the naturally occurring isotopes. = 32. therefore, the no. Germanium is a chemical element with symbol Ge and atomic number 32. Isotope abundances of germanium. Germaine is a hazardous substance UN2192 which is classified as a poisonous gas (2.3). of protons = mass number. Germanium was first located in a rare mineral called argyrodite. The number of atoms/cm 2 in Ge or Si is of the the order of 10 22. 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. 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. Atomic number (number of protons in the nucleus): 32; Atomic symbol (on the periodic table of elements): Ge Just the facts. Other compounds include: Germanium dichloride Ge Cl 2, Germanium dioxide GeO 2, Germanium tetrachloride GeCl 4 this is very irritating to eyes and membranes. SO; in your question we have: mass no. 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 … Germanium Page One. It belongs to group 14 of the periodic table and its atomic number is 32. Germanium Basic Facts . = 70. atomic no. It is a gray-white metalloid. There are five naturally occurring isotopes of germanium: germanium-70, germanium-72, germanium-73, germanium-74, and germanium-76. 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. It is less abundant than either tin or lead. Properties, sources and uses of the element germanium. Classified as a metalloid, Germanium is a solid at room temperature. 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. Isotopes differ from each other according to their mass number. It forms a large number of organometallic compounds. Overview of Germanium Germanium is a lustrous hard metalloid element, belongs to group 14 of the periodic table. It's an element that was predicted by Mendeleev in 1871. Germanium is a chemical element with Ge as its symbol. Element Germanium (Ge), Group 14, Atomic Number 32, p-block, Mass 72.630. All atoms have a mass number which is derived as follows. Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images. Common Uses It is also a flammable gas (2.1). Stable 74 Ge is the most common isotope, having a natural abundance of approximately 36%. Its ores are rare. Predicted by Mendeleev in 1870, germanium was actually found in 1886 by Winkler. Isotopes are two or more forms of an element. In pure form, the element is a grayish-white … Germanium (32 Ge) has five naturally occurring isotopes, 70 Ge, 72 Ge, 73 Ge, 74 Ge, and 76 Ge.
