Popis:	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 enthalpy values of No show the predicted metallic divalency of this element. This is confirmed by calculations with two semiempirical models developed by Eichler [1] and Miedema [2] . Using the experimentally proved correlation between adsorption and sublimation enthalpies, we calculated the No sublimation enthalpy to be 134±15 kJ mol −1 .
