Rutherfordium

naming elements, Modern atomic theory, Dubna, hafnium, Lawrence Berkeley National Laboratory

Rutherfordium, unstable chemical element with atomic number 104. In 1969 it was synthesized at the Lawrence Berkeley National Laboratory, Berkeley, California, by United States scientists who proposed the name rutherfordium, in honor of British physicist Ernest Rutherford. Russian scientists at the Joint Institute for Nuclear Research, Dubna, Russia, who claim to have synthesized the element in 1964, proposed the name kurchatovium, in honor of Russian atomic physicist I. V. Kurchatov. According to a convention adopted in 1980 for temporarily naming elements 104 and beyond, however, the element was named unnilquadium. In 1997 the International Union of Pure and Applied Chemistry (IUPAC) adopted the recommendation of the American Chemical Society to name the element rutherfordium. Modern atomic theory predicts that element 104 would be chemically similar to hafnium, but the element decays so quickly that testing its chemical properties is difficult. Many isotopes of rutherfordium have been synthesized.
