Hydrides of group 16 elements
WebGroup 16 Elements - Trends in Chemical Properties Chemistry definition Formation of hydrides of oxygen family All the elements of this group form hydrides of the type H 2E where E=O,S,Se,Te,Po. The hydrides of S, Se and Te are prepared by the action of acids on metal sulphides of H 2S, e.g., by the action of dil. H 2SO 4 on FeS.
