We say "on Earth" because elements as large as uranium come from supernova explosions elswhere in the galaxy. The isotopic abundances are probably different on different celestial bodies throughout the universe. Uranium (92U) is a naturally occurring radioactive element that has no stable isotope. It has two primordial isotopes, uranium-238 and uranium-235, that have long half-lives and are found in appreciable quantity in the Earth's crust. The decay product uranium-234 is also found. Other isotopes such as uranium-233 have been … Visa mer 1. ^ U – Excited nuclear isomer. 2. ^ ( ) – Uncertainty (1σ) is given in concise form in parentheses after the corresponding last digits. 3. ^ # – Atomic mass marked #: value and uncertainty derived not from purely experimental … Visa mer Uranium-233 is a fissile isotope of uranium that is bred from thorium-232 as part of the thorium fuel cycle. Uranium-233 was investigated for use in nuclear weapons and as a … Visa mer Uranium-235 is an isotope of uranium making up about 0.72% of natural uranium. Unlike the predominant isotope uranium-238, it is fissile, i.e., it can sustain a Visa mer Uranium-214 is the lightest known isotope of uranium.
