Controversies about the preparation of heavy elements are nothing new. While browsing through a 50-year-old issue of Nature, I came across a report describing the preparation of element-102 (Nature subscribers can see the report here). This described a multinational effort performed at The Nobel Institute of Physics, Stockholm, in which curium atoms were fused with carbon-13 atoms. The new element was named ‘Nobelium’ in honour of its place of birth.
Unfortunately, they were wrong. A year later, in 1958, the physicist Albert Ghiorso and his colleagues at Berkeley unambiguously identified nobelium-254 (the product of bombarding curium with carbon-12). They decided to retain the name of the new element – otherwise I suppose it might have become ‘Ghiorsium’, which somehow isn’t quite the same.
Speaking of dubious elements, I also recently stumbled across a spoof version of the periodic table (it comes in three parts: click here, here and here to see each section), which is worth a look if you fancy a break from the bench. This came from a BBC TV programme called ‘Look Around You’, which made fun of school science programmes from the 1970s. The rest of the web site is worth a look too – there are a few quizzes you can do, including one on iron. The answer to the question “The human body contains enough iron to make what?” was particularly illuminating.
