…its discovery. In 1997, IUPAC renamed elements 104 to 109, and gave elements 104 and 106 the Berkeley proposals rutherfordium and seaborgium. The name dubnium was given to element 105 at the same time. The 1997 names were accepted by researchers and became the standard. Rutherfordium has no stable or naturally…
