Germanium (II) hydrides. (Redirected from Germanium (II) Hydrides) Germanium (II) hydrides, also called germylene hydrides, are a class of Group 14 compounds consisting of low-valent germanium and a terminal hydride. They are also typically stabilized by an electron donor-acceptor interaction between the germanium atom and a large, bulky ligand.
Spot prices of germanium ingot have jumped nearly a third in the past month to an all-time high of 13,250 yuan ($1,826.48) a kilogram (kg) on Wednesday, data from information pr
Germane is the chemical compound with the formula Ge H 4, and the germanium analogue of methane. It is the simplest germanium hydride and one of the most useful compounds of germanium. Like the related compounds silane and methane, germane is tetrahedral. It burns in air to produce GeO 2 and water. Germane is a group 14 hydride.
The Pentagon holds a strategic stockpile for germanium but currently has no inventory reserves for gallium, a spokesperson said on Thursday, after China announced export restrictions on the two ...
Two oxides of germanium are known: germanium dioxide (GeO 2, germania) and germanium monoxide, (GeO). [4] The dioxide, GeO 2 can be obtained by roasting germanium disulfide (GeS 2) or by allowing elemental germanium to slowly oxidze in air, [5] and is a white powder that is only slightly soluble in water but reacts with alkalis to form germanates. [4]
This series has the chemical formula X 2 H 6.Ethane is commonly found alongside methane in natural gas.The other hydrides of the chemical formula X 2 H 6 are less stable than the corresponding tetrahydrides XH 4, and they are more and more less stable as X goes from carbon (ethane C 2 H 6 is stable) down to lead (or flerovium) in the periodic table (diplumbane Pb 2 H 6 is unknown [1]).
Germanium is a chemical element; it has symbol Ge and atomic number 32. It is lustrous, hard-brittle, grayish-white and similar in appearance to silicon. It is a metalloid (more rarely considered a metal) in the carbon group that is chemically similar to its group neighbors silicon and tin. Like silicon, germanium naturally reacts and forms ...
The alkaline earth metals are six chemical elements in group 2 of the periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). [ 1 ] The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure.
