This is a highly radioactive synthetic element whose most stable isotope has a half life of 16 hours (dubnium-268). This relatively high stability compared to the surrounding elements on the periodic table gives evidence that by manipulating the number of neutrons in a nucleus, one can alter the stabilities of such nuclei.
