Scientists say they've created a handful of atoms of the elusive element , which occupies a mysterious corner of the periodic table. The super-heavy element has yet to be officially named, but it is temporarily called ununpentium, roughly based on the Latin and Greek words for the digits in its atomic number, The atomic number is the number of protons an element contains. The heaviest element commonly found in nature is uranium, which has 92 protons, but scientists can load even more protons into an atomic nucleus and make heavier elements through nuclear fusion reactions. In experiments in Dubna, Russia about 10 years ago, researchers reported that they created atoms with protons. To make ununpentium in the new study, a group of researchers shot a super-fast beam of calcium which has 20 protons at a thin film of americium, the element with 95 protons. When these atomic nuclei collided, some fused together to create short-lived atoms with protons. Rudolph added that the Russian team had detected 37 atoms of element in their earlier experiments. Super-heavy elements are generally unstable and most last only a fraction of a second before they start to decay.
The extremely heavy element was just confirmed by scientists in Sweden.
All rights reserved. If you've learned all the elements from actinium to zirconium, it's time to head back to the periodic table, where there's a new, extremely heavy element in town. The new element doesn't have an official name yet, so scientists are calling it ununpentium, based on the Latin and Greek words for its atomic number, Related: Read a feature on element hunters in National Geographic magazine. In case you forgot your high school chemistry, here's a quick refresher: An element's atomic number is the number of protons it contains in its nucleus.

Just the facts
Element is an enigma of sorts. It was only added to the periodic table in , yet for decades it has attracted extra attention because of a supposed connection to extraterrestrial technology and alien lifeforms. Before we answer whether there is a connection, let's find out what element really is. As with all elements on the periodic table, the element's number corresponds to the number of protons in the nucleus of the element's atom. Gates says that element is an extremely rare element that's made one atom at a time in particle accelerators.
Moscovium is a radioactive, synthetic element about which little is known. It is classified as a metal and is expected to be solid at room temperature. It decays quickly into other elements, including nihonium. The element had previously been designated ununpentium, a placeholder name that means one-one-five in Latin. Both element names, moscovium and tennessine, honor regions where experiments linked to creating the elements took place. Moscovium was discovered in and officially announced on Feb. Moscovium has four isotopes with known half-lives, the most stable of which is Mc, with a half-live of about milliseconds. The atomic weight for manmade transuranium elements is based on the longest-lived isotope. These atomic weights should be considered provisional since a new isotope with a longer half-life could be produced in the future.
