Transuraan element. Een transuraan element is een chemisch element met een atoomnummer groter dan 92 ( uranium ). Deze elementen, vaak gezamenlijk als transuranen aangeduid, komen niet van nature op Aarde voor, omdat ze allemaal radioactief zijn met halfwaardetijden die veel korter zijn dan de leeftijd van de Aarde (4,5 miljard jaar).
10 de mar. de 2024 · Transuranium element. Transuranium elements, also known as transuranic elements, encompass a set of 26 chemical elements with atomic numbers greater than that of uranium (92). This set includes the first 11 elements beyond uranium, known as actinides, and the subsequent 15 elements, known as transactinides. With the exception of neptunium (93 ...
The elements beyond element 92 (uranium) are called transuranium elements. As of this writing, 22 transuranium elements have been produced and officially recognized by IUPAC; several other elements have formation claims that are waiting for approval. Some of these elements are shown in Table \(\PageIndex{1}\).
Transuranium element. A Transuranium element is an element with atomic number greater than 100. The term "transuranic element" is a synonym. All undiscovered elements are transneptunian elements. List of Discovered Transuranium Elements. Electron-rich nuclides decay by ejecting or neutralizing positive charge. (Fission counts as positive charge ...
All transuranium elements are radioactive with half-lives short in comparison with the Earth's lifetime, and if they were formed in cosmic processes of element synthesis, they would have disintegrated long ago. Currently, the list of transuranic elements, with each having an official name, has 26 elements.
