At the time, they were known simply as 113, 115, 117, and 118, and were assigned temporary names and symbols: ununtrium (Uut), ununpentium (Uup), ununseptium (Uus), and ununoctium (Uuo). The teams of Russian, American, and Japanese researchers behind the four new element discoveries were ...
Every element beyond uranium, for example, is named after a scientist, research institute, geographic place, or planet. Element 113, previously known by its placeholder name of ununtrium, is now nihonium (Nh). The element derives its name from “nihon,” one of two words used to say “Japan” in Japanese.

Japanse atoomchemici van het Riken-lab in Tokio kunnen hun geluk niet op nu de internationale unie van scheikundigen IUPAC hun vondst heeft erkend van een nieuw chemisch element. Dat kunstmatige en totaal instabiele element-113 komt in geen enkele scheikundedoos voor, maar de ontdekkers ...
Their discoverers will be invited to propose names for these elements, which must derive from mythology or the names of minerals, places, properties of the element, or scientists. For now, the new elements have been assigned placeholder names and symbols: ununtrium (Uut), ununpentium (Uup), ...
The International Union of Pure and Applied Chemistry notified the team of researchers at RIKEN Nishina Center for Accelerator-Based Science in Japan that it would have the honor in naming Element 113. Ununtrium, the provisional name of Element 113, is a highly radioactive element that is not found in ...

Until now, the element been known by the temporary name, ununtrium, and temporary symbol Uut. The three remaining elements, 115, 117, and 118 - known temporarily as ununpentium (Uup), ununseptium (Uus), and ununoctium (Uuo), respectively - will also get new names. The IUPAC has announced ...
Alarmingly, man-made Ununtrium, now recognised as the 113th element on the periodic table, as it is currently called, could potentially be used to make nuclear warheads more devastating than those produced with plutonium such as the implosion-type fission bomb exploded over the Japanese city of ...

Here are 10 things you should know about element 113, the first element to be discovered and named by researchers in Asia, and its founder, Kosuke Morita: ——. 1. Element 113 goes by the temporary name of ununtrium and the temporary symbol Uut. It sits between copernicium (Cn) and flerovium (Fl) on ...
Riken had earlier said japonium might be proposed as a name for element 113, which provisionally had been named ununtrium. However, Morita has no specific candidates under consideration. He said he planned to spend part of next year considering a name for the element. The IUPAC group gave ...
Until now, the elements have gone by either their atomic weights (the numbers) or placeholder names based on their order: ununtrium, ununpentium, ununseptium, and ununoctium. Along the way, they've collected various other nomenclatures — ununoctium has been called eka-radon, following in Dmitri ...
Nihonium 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. The element, No. 113 on the Periodic Table of Elements, had previously been designated ununtrium, a placeholder name that means one-one-three in Latin.
Almost immediately after the Swedish scientists created it by smashing twenty-proton calcium nuclei into ninety-five-proton americium nuclei at high speed, the ununpentium decayed into element 113—ununtrium—which itself decayed into lighter elements. Its half-life was found to be only a hundred and ...
Though ununtrium is an exciting breakthrough, evidence for synthesized elements up to number 118 in the periodic table has been found. Earlier this year, elements 114 and 116 were officially named by IUPAC. Element 114 has been dubbed flerovium (in honour of the Flerov Laboratory, Russia) and ...
Scientists in Japan think they've finally created the elusive element 113, one of the missing items on the periodic table of elements. Element 113 is an atom with 113 protons in its nucleus — a type of matter that must be created inside a laboratory because it is not found naturally on Earth. Heavier and ...
