1963

Bedreag's Système Physique Des Éléments

From Le Journal De Physique Et Le Radium, 24, pp27 (1963).

After a short historical account of the evolution of the periodic system Bedreag analyses some properties of various groups of elements: density, spectra, ionic radii, ionization potentials and so on, arguments are given in favour of the division of the transuranic elements into "uranides" and "curides".

Thanks to René for the tip!
