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 ...
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 into ...
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, ...
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), ...
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 ...
Le terme « ununoctium » (du latin un-un-hui) était la dénomination temporaire attribuée à l'élément chimique transuranien - c'est-à-dire plus lourd que l'uranium - de numéro atomique 118. Depuis ...
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 ...
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 ...
