PROBLEM TO BE SOLVED: To provided a fluorine compound/hydrogen storage alloy composite body which has a water-repelling effect and can absorb hydrogen gas efficiently. SOLUTION: The material of the present invention is a fluorine compound- hydrogen storage alloy composite body produced by coating ...
HBr and Hl were not yet known, fluorine was not to be isolated until 1886, and Lavoisier, in keeping with his system, merely postulated that chlorine was the as yet undecomposed oxide of an element that he called themuriaticradicalormuriaticum. HBr 和 Hl 那时还不为人所知,氟直到 1886 年...
One fluorine atom has its inner orbital shell filled with two electrons, and the outer shell has seven. Fluorine will share the one electron of hydrogen to fill the orbital to fulfill the octet rule of eight electrons. However, since fluorine has a high electronegativity, this is known to ...

It mayhave been made earlier in 1670 by Schwankhard in the process of etchingglass using fluorspar and acid.Hydrogen fluoride is the most important fluorine compound, in terms ofamounts produced and the vast number of uses. The largest application of thiscompound is in the manufacture of ...
Hydrogen has been used as a primary rocket fuel forcombustionwith oxygen orfluorineand is favoured as a propellant for nuclear-powered rockets and space vehicles. Another increasing use of hydrogen is in the direct reduction ofironores tometalliciron and in the reduction of the oxides oftungstenan...
(Chemistry) a weak chemical bond between an electronegative atom, such as fluorine, oxygen, or nitrogen, and a hydrogen atom bound to another electronegative atom. Hydrogen bonds are responsible for the properties of water and many biological molecules ...
