Germane, Germanium hydride, Germanomethane, Monogermane [Note: Used chiefly for the production of high purity germanium for use in semiconductors.] In pure form, the element is a grayish-white metalloid. The table shows element percentages for GeSe (germanium selenide). i.e. Germanium and … The number of electrons in each of germanium's shells is 2, 8, 18, 4 and its electron configuration is [Ar] 3d 10 4s 2 4p 2 . Find Freezing point of Ge (Germanium) or Find freezing point of different substance like freezing point of water, hydrogen, carbon, nitrogen, sodium, aluminum, iron, zinc, helium, silver, gold, mercury, lead, iodine, platinum and many more Ge is a metalloid having a crystal structure similar to that of the diamond. Germanium tetrachloride is then hydrolyzed and dried, producing germanium dioxide (GeO2). Atomic Mass 72,61 Learn more about the atomic mass. Germanium(4+)tetrac hlorid [German] [ACD/IUPAC Name] Germanium(IV) chlor ide. See more Germanium products. Experiments were performed in the organic solvents trioctylamine, squalene, and octacosane, which have boiling points in the temperature range from 380 to 429 °C. Germanium (atomic symbol: Ge, atomic number: 32) is a Block P, Group 14, Period 4 element with an atomic weight of 72.63. Predicted data is generated using the US Environmental Protection Agency’s EPISuite™. Find Boiling point of Germanium (Ge) or Find boiling point of different substance like boiling point of water, hydrogen, carbon, nitrogen, sodium, aluminum, iron, zinc, helium, silver, gold, mercury, lead, iodine, platinum and many more Germanium (Ge), a chemical element between silicon and tin in Group 14 (IVa) of the periodic table, a silvery-gray metalloid, intermediate in properties between the metals and the nonmetals.Although germanium was not discovered until 1886 by Clemens Winkler, a German chemist, its existence, properties, and position in the periodic system had been predicted in 1871 by the Russian … It is a semiconductor.

Notable characteristics . The element is mostly distributed in nature, but it’s too reactive to occur free. 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. [Note: Shipped as a compressed gas.] Germanium, a chemical element places between silicon and tin in Group 14 of the periodic table. Boiling Point: 3103K 2830 ... Germanium - Ge (EnvironmentalChemistry.com)- Comprehensive information for the element Germanium - Ge is provided by this page including scores of properties, element names in many languages, most known nuclides … The oxide is then reduced with hydrogen to form germanium metal powder. * Boiling Point Notes: 1. It is a poor conductor of electricity but has exceptional properties as a semiconductor material and it is in this area where germanium is primarily used. The boiling point is 2830.0 °C. Boiling point The temperature at which the liquid–gas phase change occurs. The boiling point quoted is when the vapor pressure of graphite vapor above subliming graphite reaches 1 atmosphere. Germanium itself is classified as a metalloid. Germanium is a hard, grayish-white element that has a metallic luster and the same crystal structure as diamond.In addition, it is important to note that germanium is a semiconductor, with electrical properties between those of a metal and an insulator.In its pure state, this metalloid is crystalline, brittle and retains its lustre in air at room temperature. Colorless gas with a pungent odor. when heated, carbon undergoes a phase change directly from solid to gas. Germanium powder is cast into bars at temperatures over 1720.85 °F (938.25 °C).
