what is the oxidation state of ge in geh4
Germanium Elemental germanium oxidizes slowly to GeO2 at 250 °C.[32] Germanium is insoluble in dilute acids and alkalis but dissolves slowly in hot concentrated sulfuric and nitric acids and reacts violently with molten alkalis to produce germanates ([GeO3]2−). Germanium occurs mostly in the oxidation state +4 although many +2 compounds are known.[33] Other oxidation states are rare: +3 is found in compounds such as Ge2Cl6, and +3 and +1 are found on the surface of oxides,[34] or negative oxidation states in germanes, such as −4 in GeH4. Germanium cluster anions (Zintl ions) such as Ge42−, Ge94−, Ge92−, [(Ge9)2]6− have been prepared by the extraction from alloys containing alkali metals and germanium in liquid ammonia in the presence of ethylenediamine or a cryptand.[33][35] The oxidation states of the element in these ions are not integers—similar to the ozonides O3−.
Rubidium oxide The final product of oxygenation of Rb is principally RbO2, rubidium superoxide:
