Los elementos transuránicos o elementos transuránidos son elementos químicos con número atómico mayor que 92, el número atómico del elemento uranio. 1 El nombre de trans-uránidos significa «más allá del uranio».
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.
17 de ago. de 2020 · The element, named mendelevium after Russian chemist Dimitri Mendeleev, was the first element discovered a single atom at a time . By the 1950s, accelerator science had also advanced to the point that even more exotic nuclei, including those past the actinides, could theoretically be created.
