Radioaktive Elemente: Actinoide

Henry Moseley, X-ray spectroscopy and the periodic table

Although the discovery of artificial radioactive elements with Z > 92 again depended on nucleosynthesis and radiological characterization, measurement of the frequencies or energies of characteristic X-rays remains the ultimate goal in proving the existence of an element.

100 years of nuclear isomers—then and now

The suggestion that some atomic nuclei would be able to exist in more than one stable or metastable configuration was proposed by Soddy in 1917. Subsequently, the first experimental example of such

Chemistry’s Decision Point : Isotopes

Although the modern periodic table barely resembles the one constructed by Dmitri Mendeleev, every chemistry student learns that the placement of missing elements in the open slots of Mendeleev’s t

Radioactive Decay Chains

Unique decay characteristics of the first isotopes were measured before the concept of isotopes was developed. The chapter describes the first observations of radioactivity and the subsequent

First structural characterization of Pa(iv) in aqueous solution and quantum chemical investigations of the tetravalent actinides up to Bk(IV): the evidence of a curium break.

The combined results of EXAFS data and quantum chemically optimized structures suggest that the Pa(4+) aqua ion has an average of nine water molecules in its first hydration sphere at a mean Pa-O distance of 2.43 Å, demonstrating that Pa(iv) resembles its early actinide neighbors.
