ununpentium

Elements 115 and 117, formerly called ununpentium and ununseptium, are now moscovium (Mc) and tennessine (Ts), respectively. The two elements were synthesized by a team of American and Russian scientists and named after the sites of their discovery. Moscovium honors the Joint Institute for ...

The elements have the temporary names of ununtrium, ununpentium, ununseptium and ununoctium, which really roll off the tongue. The teams that discovered them can now set about giving them official names. "To scientists, this is of greater value than an Olympic gold medal," Nobel laureate Ryoji Noyori, ...

The radioactive ununpentium (a temporary name meaning “one-one-five”) existed for only a fraction of a second before decaying into other elements. Next, physicists and chemists will try to make more of the mysterious metal to explore its “table manners” — its properties and structure. [This article originally ...

We're getting closer to the end, my peeps! This week's element goes by the temporary name, ununpentium, and the temporary atomic symbol, Uup, along with the permanent atomic number, 115. This element is predicted to be a solid at room temperature, but it is not known whether it has the chemical ...

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 ...

The new evidence will be reviewed by the International Union of Pure and Applied Chemists (IUPAC), and if confirmed, element 115 will likely be given a new name and added to the Periodic Table of Elements. Its temporary name, which is being used as a placeholder, is ununpentium. Element 115 is one ...

When the Russian chemist Dmitri Mendeleev published his periodic table of elements in 1869, there were just fifty-nine entries on it. The table grouped those elements—hydrogen, oxygen, and carbon, along with less familiar substances like osmium, rhodium, yttrium—according to their shared chemical ...

Ununpentium was originally created by Russian scientists in 2004. For an element to be officially discovered, though, a second group must replicate the work — which is what the Lund University chemists have done. Now that ununpentium has been confirmed, the IUPAC (International Union of Pure and ...

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, 115. (Related: Read a feature on element hunters in National Geographic magazine.) In case you forgot your high school chemistry, here's a quick ...

Ununpentium was discovered in 2003 by a group of scientists working at the Joint Institute for Nuclear Research in Dubna, Russia, and Lawrence Livermore National Laboratory (LLNL), California. The group was headed by Yuri Oganessian and Ken Moody. As of now, the results for this element do not ...
