Ununoctium, more commonly known as element 118, has had a tumultuous life. In 1999 a group at Lawrence Berkeley National Labs (LBNL) announced that by smashing krypton ions (86 36 Kr) into a lead (208 ...

Isotopes Ununoctium is likely to have only one isotope known as Ununoctium-294. Ununoctium-294 is Ununoctium’s most stable isotope and has a half-life of about 0.89 milliseconds. Ununoctium-294 decays ...

Oganesson is a radioactive, artificially produced element about which little is known. It is expected to be a gas and is classified as a non-metal. It is a member of the noble gas group. The element, ...

For the second time in seven years, researchers say they have made the heaviest chemical element ever — the exotically titled ununoctium, or element 118. The evidence comes in the form of specific ...

Ununtrium, ununpentium, ununseptium and ununoctium are the tentative names for the four newest members of the periodic table of elements. The International Union of Pure and Applied Chemistry (IUPAC), ...

There are 118 elements in the periodic table, from hydrogen to ununoctium. Chemists at the University of Nottingham set out to produce videos explained each one (available at The Periodic Table of ...

Des années de recherche, des résultats controversés, des accusations de fraude, la course à l'atome le plus lourd méritera un jour un roman. Nouvel épisode cette semaine : le désormais mythique ...

Des chercheurs ont réussi à fabriquer un élément inédit, le «118». De quoi compléter la fameuse table périodique de Mendeleïev. Tableau périodique. Table de Mendeleïev. Ou classification périodique ...

Motivée par la quête de l'îlot de stabilité, la recherche des éléments superlourds a été relancée à la fin des années 1990 par la synthèse de l'élément de numéro atomique 114 (ununquadium) en 1998 à l ...

In some sense, what you might have suspected from the first day of high-school chemistry is true: The periodic table is a colossal waste of time. Nine out of every 10 atoms in the universe are ...

Jusqu'en 1962, les seuls « composés » de gaz nobles connus étaient des clathrates et des hydrates. Des composés de coordination avaient également été observés, mais uniquement par spectroscopie, sans ...
