One element that scientists competed to discover was dubnium. The discovery of dubnium (element 105), like that of rutherfordium (element 104), has been a matter of dispute between Soviet and American scientists. They are similar with those of other group 5 elements. As it is so unstable, any amount formed would decompose to other elements so quickly that there’s no reason to study its effects on human health. It is named after the town of Dubna in Russia (north of Moscow), where it was first produced.
