Germanium definition, a scarce, metallic, grayish-white element, normally tetravalent, used chiefly in transistors. It is a semiconductor. The boiling point quoted is when the vapor pressure of graphite vapor above subliming graphite reaches 1 atmosphere. Germanium Overview Germanium Boiling Point 2830°C Atomic Number 32 Learn more about the atomic number. Germanium is a solid at twenty degrees. Germanium and the oxide are transparent to infrared radiation. Log Octanol-Water Partition Coef (SRC): Log Kow (KOWWIN v1.67 estimate) = 1.12 Boiling Pt, Melting Pt, Vapor Pressure Estimations (MPBPWIN v1.42): Boiling Pt (deg C): 482.98 (Adapted Stein & Brown method) Melting Pt (deg C): 188.60 (Mean or Weighted MP) VP(mm Hg,25 deg C): 4.24E-009 (Modified Grain … Germane, Germanium hydride, Germanomethane, Monogermane [Note: Used chiefly for the production of high purity germanium for use in semiconductors.] The boiling point is 2830.0 °C. DeltaH^o - TDeltaS^o = 0 at Equilibrium (i.e., boiling point) and 'T' is the Thermodynamic Boiling Point for the phase transition. In pure form, the element is a grayish-white metalloid. ... Germanium falls in the same group as carbon and silicon, but also as tin and lead. Germanium, a chemical element places between silicon and tin in Group 14 of the periodic table. Geometry of germanium: 3 coordinate: pyramidal Prototypical structure: Element analysis. It has a melting point of 937.4°C (1,719°F) and a boiling point of 2,830°C (5,130°F). Colorless gas with a pungent odor. Germanium powder is cast into bars at temperatures over 1720.85 °F (938.25 °C). when heated, carbon undergoes a phase change directly from solid to gas. 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. A hard, grey-white, lustrous and brittle metalloid acts in properties between metals and nonmetals. It is hard, brittle and has a grey-white colour. n. ... as an alloying agent and catalyst, and in certain optical glasses. [Note: Shipped as a compressed gas.] Germanium is stable in air and water and is unaffected by alkalis and acids, with the exception of nitric acid. Reaction of GeF 4 with fluoride sources produces GeF 5 − anions with octahedral coordination around Ge atom due to polymerization. When working in vacuum one must recognize that even if the work is not at the boiling point for the substance there is ... Germanium Ge 1719 937 Gold Au 1947 1064 Hafnium Hf 4051 2233 Indium In 314 157 The table shows element percentages for GeSe (germanium selenide). It is less abundant than either tin or lead. i.e. Atomic number 32; atomic weight 72.64; melting point 938.3°C; boiling point 2,833°C; specific gravity 5.323 (at 25°C); valence 2, 4. Germanium tetrachlo ride. See more Germanium products. Atomic Mass 72,61 Learn more about the atomic mass. It conducts an electric current poorly. Note that, these points are associated with the standard atmospheric pressure.. Boiling Point – Saturation. Notable characteristics . Chemically similar to tin, germanium is an important semiconductor material. Boiling point The temperature at which the liquid–gas phase change occurs. From DeltaH^o-TDeltaS^o = 0 => Equilibrium Conditions => DeltaH^o = TDeltaS^o => T = (DeltaH^o"/"DeltaS^o") DeltaH^o = sumn*DeltaH^o(Products) - sumn*DeltaH^o(Reactants) DeltaS^o = sumn*S^o(Products) - sumn*"S^o(Reactants) Example: … 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. Solid state structure. But it is brittle and breaks apart rather easily, which metals normally do not do. * Boiling Point Notes: 1. It has a bright, shiny, silvery color. Experiments were performed in the organic solvents trioctylamine, squalene, and octacosane, which have boiling points in the temperature range from 380 to 429 °C. 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. It reacts with water to form hydrofluoric acid and germanium dioxide. Ge nanoparticles with sizes from 1 to 15 nm were synthesized by thermal decomposition of the germane precursors trichlorogermane, tetraethylgermane, and tetrabutylgermane. Define germanium. 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.
