Mendelevium electron configurations

This oxidation state was indicated in the cocrystallization of Md with CsCl and RbCl after the coreduction of Md + and Sm + with Mg in an ethanol-7 M HC1 solution. Mendelevium was also found enriched in Rb2PtCl precipitates, a specific carrier for the larger ions of the alkali metals. These results were explained by a stabilization of the monovalent ion due to completing the f shell which would give the 5f- electronic configuration.

The electronic structure of the ground state of gaseous mendelevium atoms has been predicted to be the F7/2 level of the 5f 7s configuration [42]. Experimental confirmation has not yet been attempted. No experimental measurements of inner-shell binding energies or x-ray energies have been reported.
