which are in turn different from those ofgold. Every element is designated by a unique symbol consisting of one, two, or three letters arising from either the current element name or its original (often Latin) name. For example, the symbols for carbon,hydrogen, andoxygenare simply C, H, ...
[18] confirmed the placement of Rf as the first transactinide element into group 4 of the Periodic Table by conducting the first liquid phase separations with a Rutherfordium (Rf, Z=104) From the systematic investigation of ion-exchange chromatographic behavior of Rf, based on an atom-at-a-...
The first transuranium element (element with atomic number greater than 92) discovered was neptunium in 1940. As of February 2010, only the elements up to 112, copernicium, have been confirmed as discovered by IUPAC, while more or less reliable claims have been made for synthesis of elements...
