The chemical properties, ion exchange behavior, oxidation states, ion types and stability, ionic radii, electronic structure, and crystal structure of the 14 actinides (plus actinium) and 14 lanthanides (plus lanthanum) are discussed on comparative basis. The analogous positions of these two groups of elements in the periodic table are discussed. Also included are tables identifying the discoverers of these 30 elements and a discussion of the practical application of many of them.

“…1. According to the literature, REEs can be concentrated in Fe±Mn oxides during natural weathering, soil formation and sedimentation (Moeller, 1973). Therefore, a greater concentration of REEs in fraction B2 was expected to be observed for soil no.…”

“…Based on extrapolation of the DTG curve, the second step began near 330°C and, based on the upward slow mass gain trend, would have produced a non-volatile lanthanum oxyfluoride having the nominal composition La 3 O 2 F 5 . Brown (1968) and Moeller (1973) both report the existence of LaF 3 and LaOF, but they do not report any intermediate oxyfluorides. The product needs to be characterized to confirm its final composition.…”

“…Brown (1968) reported the preparation of CeF 4 by fluorine treatment of the trifluoride and the oxide. Moeller (1973) reported the preparation of CeF 4 from the trifluoride. Brown reported that no oxyfluorides of the tetravalent lanthanides or actinides other than ThOF 2 have been observed.…”
