Hi folks - Here is the Friday Element Quiz Answer: The Question: This element has a very contentious history pertaining to who actually first discovered it. This element has been produced by bombarding americium-243 with neon-22 atoms and bombarding californium-249 with nitrogen-15 atoms. The element was "finally" named in 1997. The longest lived isotope of this element has a half life of 34 seconds. Bonus Question: List the two names that were used for this element prior to 1997. The Answer: The element is Dubnium (Db). There was a period of element discovery in the late 1960s thru the late 1970s where there was considerable confusion and contention on who discovered what transfermium elements. Db was caught up in that chaos. The scientists at JINR in Dubna Russia claimed discovery in 1967, then the scientists at UC Berkeley USA claimed discovery in 1970. The credit and naming issue was resolved in 1997. The bonus question answers are nielsbohrium (Ns) and hahnium (Ha) which were both used for a period time until 1997. I don't believe the committee ever considered Doug's "dummynium" as a viable naming option. The quiz winner is Ahne Oosterhof of A-Laser so Clumpy and Kloumpios will fire up the tractors and head for Milpitas CA (???) for a week of service.
