It serves no purpose except in research. What is known is that it is highly radioactive with the longest lasting isotope being Rg 281 with a half life of 22.8 seconds. It is only made by fussing nickel and bismuth in a heavy ion collider. ]]> 2017-10-31 15:34:56 UTC https://padlet.com/chrisrforstrom/Roentgenium/wish/202196090
