Examples of transuranium in the following topics:
-
- Transuranium elements are those beyond uranium, none of which is stable because of radioactive decomposition.
- In chemistry, transuranium elements, also known as transuranic elements, are the chemical elements with atomic numbers greater than 92, which is the atomic number of uranium.
- Transuranium elements that can be found on Earth now are artificially-generated, synthetic elements made via nuclear reactors or particle accelerators.
-
- In 1934, Enrico Fermi predicted the existence of transuranium elements—those elements with atomic number (z) greater than or equal to 93.
- The first transuranium element, Np (neptunium), was synthetically produced in 1940 by bombarding uranium with slow neutrons.
- Experiments in the synthesis of transuranium elements continue.
