The chemical formula for hydrogen fluoride is HF. One hydrogen atom has one electron and one fluorine atom has nine electrons. These atoms will share one electron in the outer electron orbital in a polar covalent bond. One fluorine atom has its inner orbital shell filled with two electrons, ...
Hydrogen fluoride (CAS NO.7664-39-3) is a chemical compound with the formula HF. It is the principal industrial source of fluorine, often in the aqueous form as hydrofluoric acid. The hot, gaseous hydrogen fluoride (CAS NO.7664-39-3) is either absorbed in water or liquefied; refrigeration...
A colorless, fuming corrosive liquid or a highly soluble corrosive gas, HF, that is extremely toxic, used in the manufacture of hydrofluoric acid, as a reagent, catalyst, and fluorinating agent, and in the refining of uranium and the preparation of many fluorine compounds. ...
