Elemento transurânico. Em química, elemento transurânico é o elemento químico artificial com número atômico maior do que 92, o número atômico do urânio, vindo depois deste na tabela periódica. [ 1] . Todos estes átomos são instáveis devido aos seus grandes núcleos, portanto são radioativos.
Bibliography. External links. Einsteinium is a synthetic chemical element; it has symbol Es and atomic number 99. It is a member of the actinide series and it is the seventh transuranium element. It was named in honor of Albert Einstein . Einsteinium was discovered as a component of the debris of the first hydrogen bomb explosion in 1952.
transuranium element, any of the chemical elements that lie beyond uranium in the periodic table—i.e., those with atomic numbers greater than 92. Twenty-six of these elements have been discovered and named or are awaiting confirmation of their discovery. Eleven of them, from neptunium through lawrencium, belong to the actinoid series.
