It is not attacked by air, bromine, cold aqueous alkaHs, dilute acids, concentrated hydrochloric acid and sulphuric acid. It is decomposed by chlorine gas and concentrated nitric acid. It reacts with fluorine at —75 °C to form chromium hexafluoride. [Pg.208]

Chromium is the only metal of the first transition series to form a hexafluoride (3). The compound is so unstable that no solid-state characteristics have been recorded. The metals of the second and third transition series form hexafluorides which, structurally as a group, are the most closely related of all the transition metal fluorides. These compounds are molecular species, with an essentially regular, octahedral arrangement of fluorine atoms around the metal atom. This leads... [Pg.106]

Element 106. The chemical properties of element 106 (eka-tungsten) are predicted to be similar to those of tungsten, molybdenum and to some extent chromium, offering an even richer chemistry of complex ions than these elements. The hexafluoride should be quite volatile and the hexachloride, pentachloride and oxychloride should be moderately volatile. Penneman and Mann predict a -)-4 oxidation state in aqueous solution. Jprgensen s selection of k is for the hydrated cation and is not intended to account for the effects of complex ion formation. However, since tungsten is stabilized in the oxidation state of -t-6 by the tungstate ion, an analogous situation may be expected for element 106. [Pg.115]
