The Periodic Table-1923 & 1998

The past 75 years have been some of the richest ever for the discovery of new elements. Since C&EN began publication in 1923, 26 elements have been added to the periodic table. On average, that's about one new element every three years. The era spans a major change in the kind of elements being discovered. Hafnium (discovered in 1923) and rhenium (in 1925) were the last elements with stable nuclei to be added to the periodic table. Beginning with technetium, in 1937, the new elements are radioactive in all of their isotopes. All but one of them were discovered shortly after they were artificially produced through nuclear transmutation reactions, although some, such as neptunium and plutonium, were later found also to occur in nature. With the discovery of hafnium, element 72, the then-new field of atomic physics was becoming crucial to the discovery of new elements. Although not a rare element, hafnium was nearly ...

Nuclear Transmutation Reaction Occurring during The Light Water Electrolysis on Pd Electrode

Certain amounts of unexpected elements, eg. Au, Fe, Cu, Zn, and K withthe different isotopic contents evidently different from their natural isotopicabundance were found to be produced on/in Pd electrode by the light waterelectrolysis. The amounts of Fe and Cu reached several at. percent in the vicinity of the electrode surface. The amounts of Zn, Au and K were somewhatsmaller. These elements were distributed locally along the scraped edge of theelectrode. The distribution of Au was completely overlapping with that of Ptpartially deposited on the scraped edge of the Pd electrode.
