Although most compounds are referred to by their IUPAC systematic names (following IUPAC nomenclature), "traditional" names have also been kept where they are in wide use or of significant historical interests.Solubility table
The table below provides information on the variation of solubility of different substances (mostly inorganic compounds) in water with temperature, at 1 atmosphere pressure. Units of solubility are given in grams per 100 millilitres of water (g/100 ml), unless shown otherwise. The substances are listed in alphabetical order.Thallium(I) fluoride
Thallium(I) fluoride (or thallous fluoride or thallium monofluoride) is the chemical compound composed of thallium and fluorine with the formula TlF. It consists of hard white orthorhombic crystals which are slightly deliquescent in humid air but revert to the anhydrous form in dry air. It has a distorted sodium chloride (rock salt) crystal structure, due to the 6s2 inert pair on Tl+.Thallium(I) fluoride is unusual among the thallium(I) halides in that it is very soluble in water, while the others are not.
