Nouvel épisode cette semaine : le désormais mythique ununoctium, l‘élément 118, aurait été aperçu. Mais la communauté scientifique reste dubitative… Si l'on sait comment se ...

En 2006, une équipe américano-russe a ainsi réussi à produire trois atomes d'ununoctium, formé de 118 protons et 176 neutrons, resté stable pendant... 0,89 milliseconde ! La traque de l ...

The elements were first synthesised between 2002 and 2010 and were temporarily named ununtrium, ununpentium, ununseptium, and ununoctium. By December 2015, IUPAC recognised their discovery and allowed ...

Brahmanand was required to memorise and type names of all elements - starting from the first element ‘hydrogen’ to the 118th ‘Ununoctium’ - within the specified period in an online ...

It is a member of the noble gas group. The element, No. 118 on the Periodic Table of Elements, had previously been designated ununoctium, a placeholder name that means one-one-eight in Latin.

IUPAC decided to let the names stand, and unwieldy placeholder names — ununtrium, ununpentium, ununseptium and ununoctium — assigned when the elements were added to the periodic table in ...

Unwieldy placeholder names — ununtrium, ununpentium, ununseptium and ununoctium, assigned when the elements were added to the table in December 2015 — can now be scrubbed. The new names ...

To solve the puzzle I was on, all I had to do was get two heavy containers of an element, ununoctium to be specific, and drop them on to a hanging table. This was way more challenging than it sounds, ...
