| First created in 1984, hassium doesn't exist in nature--it must be made by combining the nuclei of lighter elements. In February, the International Union of Pure and Applied Chemistry (IUPAC) released a new roster of proposed names for the elements numbered 104 to 109: rutherfordium (104), dubnium (105), seaborgium (106), bohrium (107), hassium (108), and meitnerium (109). Meanwhile Lazarev and his coworkers are bombarding uranium with sulfur nuclei to create what they hope will be new, longer-lived isotopes of element 108, hassium. |
