Abstract
The adsorption of elemental No on Ti, V, Nb, Ta and Mo was studied in comparison to Cf, Es and Fm by thermochromatography. The adsorption en thalpy values of No show the predicted metallic divalency of this elem ent. This is confirmed by calculations with two semiempirical models d eveloped by Eichler [1] and Miedema [2]. Using the experimentally prov ed correlation between adsorption and sublimation enthalpies, we calcu lated the No sublimation enthalpy to be 134 +/- 15 kJ mol(-1). (C) 199 8 Elsevier Science S.A.
