Dihydrogen, under certain reaction conditions, combines with almost all elements, except noble gases, to form binary compounds, called hydrides. If 'E' is the symbol of an element, then hydride can be expressed as EH_x (e.g.HgH_2) or E H_x (e.g. B_2H_6) . The hydrides are classified into three categories : ionic, covalent and metalic Classify the following as covalent, Ionic or polymer interstitial hydrides
