Web7 apr. 2024 · Le Lawrencium est un nom qui a été choisi en hommage à Ernest Lawrence, physicien américain inventeur du cyclotron, lauréat du prix nobel de physique en 1939 et fondateur du laboratoire Berkeley à l'origine de nombreux travaux de recherche sur les transuraniens. Ce nom fut définitivement validé par l'UICPA en 1997. WebLawrencium, grundstof nr. 103; atomtegn Lr. Lawrencium er en af transuranerne og det sidste af actiniderne. Ved at bombardere californiumisotoper med borkerner lykkedes det forskere ved Lawrence Berkeley Laboratory i Californien i 1961 at fremstille lawrencium (258Lr), ganske vist i små mængder. 258Lr har en halveringstid på 4,3 s.
