Admittedly, if you’re not a chemist or physicist, you may find this post as boring as dirt. (Please forgive the simile, microbiologists. I know dirt is actually fascinating.) Then again, it’s not everyday a new element is added to the periodic table.
The latest addition, number 112, was discovered on February, 9th, 1996 at 10:37 PM by a team under Professor Sigurd Hofmann at the GSI Helmholtzzentrum fÃ¼r Schwerionenforschung (Center for Heavy Ion Research) in Darmstadt, Germany, who confirmed its existence by observing a characteristic “decay chain” of radioisotopes (illustrated above) that could only have originated with element 112.
Just a couple weeks ago, on February 19, that discovery was officially confirmed by the International Union of Pure and Applied Chemistry (IUPAC), who accepted the GSI team’s recommendation of the name “Copernicium” in honor, naturally, of Nicolaus Copernicus, whom most will recall as the first scientist to stand up and declare that the earth revolves around the sun, rather than the other way ’round. The new two-letter symbol is “Cn.”Continue Reading

I found this introduction to the elements, and a breakdown of the periodic table on Chem4Kids – lots more interesting stuff on their site. As far as we know, there are only so many basic elements. Up to this point in time we have discovered/created over 100. While there may be more out there to […]Continue Reading
The University of Nottingham has produced a series of YouTube videos, each about a different element. Here’s their YouTube channel (via BoingBoing), and here is their website for more information. I poked around a bit and found out that there’s a documentary being made about the scientists, and they’re posting wonderful snippets here. They’re really […]Continue Reading
