In November 2016, the international Union of Pure and Applied Chemistry (IUPAC) officially approved the name “moscovium”, which was named after Russian capital city, Moscow (Anthony, Element 115: How chemists discovered the newest member of the periodic table, 2013) The temporary name “ununpentium”, in Greek, means “115”. It filled in the 115 th empty square in the periodic table, which marked a great break through in the field of super-heavy element. On February 2, 2004, a new element, ununpentium was officially announced to become the 115 th element in the periodic table. The process has been shown in the photo, which describes the process when the calcium ions targets the Americium atoms. As the element was created, an international research team led by the Lund University scientists tested and confirmed that a new element could be created from the bombardment of calcium ions and americium atoms. That is why I chose to draw a flag of France and a flag of America on the wall to show that this element was first created by the international institute. It is first discovered by the scientists at the Joint Institute for Nuclear Research in Dubna, Russia and scientists at the Lawrence Livermore National Laboratory in California in 2003 (Sharp, 2016).

If further study shows it really, really exists, an international committee will decide which of its many discoverers around the world will get naming rights. HERZBERG: It could well be that there are elements that live long enough to make milligram or microgram quantities eventually and do something with them.īRUMFIEL: In the meantime, 115 doesn't even have a name. They can stick around for minutes, days, maybe even years. Elements on this island are even heavier than 115, but strange quantum effects keep them from breaking apart. Nuclear researchers call it the island of stability. It really is a down-to-earth element 115.īRUMFIEL: But 115 could be on the edge of something really magical. HERZBERG: It has nothing, nothing whatsoever to do with antigravity devices or spaceships or anything else.
So what's this exotic new element good for? The work will appear in Physical Review Letters. and Japan, have detected an X-ray signal that makes it much more likely 115 exists, if only briefly. Now, Herzberg at the University of Liverpool in the U.K., together with colleagues in Europe, the U.S.
They couldn't measure it before it blew itself apart. Russian scientists first spotted it a few years ago, but they couldn't be sure. And that is why it is very, very difficult to create these super-heavy elements.īRUMFIEL: In fact, that's one reason element 115 isn't official. HERZBERG: If you just put positive charges into it, you get something that tries to rip itself apart eventually. This creates big new elements packed to the brim with positively charged protons. Scientists start with elements that already exist in nature and combine them together. HERZBERG: What you get out is a perfectly baked cake.īRUMFIEL: Or if you're a nuclear physicist like Herzberg, a new element, element 115. RODI HERZBERG: You take all the ingredients and then you throw them all together in a very controlled way.īRUMFIEL: If you've done your whisking, set the oven at just the right temperature. GEOFF BRUMFIEL, BYLINE: Rodi Herzberg says making super-heavy elements is just like baking.ĭR. But as NPR's Geoff Brumfiel reports, the researchers say even heavier elements may be just around the corner. Element 115 doesn't even have a name yet. Scientists say they've created one of the heaviest chemical elements ever seen. Remember the periodic table from your school days? Well, it's still growing.
