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) and plutonium (94), all transuranium elements are synthetic, meaning they are not naturally found on Earth but are created artificially. These elements are highly unstable and undergo radioactive decay processes, transforming into other elements over time.
Transuranium elements, due to their highly unstable nature, are highly radioactive, and they emit various types of radiation as they undergo decay. These elements experience radioactive decay processes, such as alpha decay, beta decay, and in some cases, spontaneous fission, which leads to the transformation of the transuranium elements into other elements. These radioactive properties make them valuable for various applications, including medical diagnostics, nuclear power generation, and scientific research. However, the short half-lives and hazardous nature of transuranium elements pose significant challenges for their handling and containment. As a result of their synthetic nature, transuranium elements are produced in laboratories through nuclear reactions involving heavy elements as target materials, which makes them important subjects of study in the field of nuclear chemistry.
