Uranium (92 U) is a naturally occurring radioactive element (radioelement) with no stable isotopes. It has two primordial isotopes, uranium-238 and uranium-235, that have long half-lives and are found in …

Data, values and properties of the individual nuclides respectively isotopes of Uranium.

All of the uranium isotopes decay to shorter-lived decay products often referred to as “daughters.” U-238 and U-235 together with their decay products form a “decay chain” or “series” the final decay product …

Natural uranium is constituted primarily of uranium-238 with 0.7% uranium-235 and a small amount of isotope 234. Three isotopes, uranium 236, 233 and 232, are also produced by reactors from uranium …

Jan 22, 2026 · For example, uranium has thirty-seven different isotopes, including uranium-235 and uranium-238. : U-238, U-235 and U-234. Uranium is weakly radioactive and contributes to low levels …

Uranium is a chemical element with the symbol U and the atomic number 92. There are three naturally occurring isotopes of uranium: uranium-238, the heaviest and most abundant, uranium-235 and …

Naturally occurring uranium is composed of three major isotopes, uranium-238 (99.28% natural abundance), uranium-235 (0.71%), and uranium-234 (0.0054%).

All known isotopes of Uranium (U), element 92. Includes mass, abundance, half-life, spin/parity, and decay modes.

This WebElements periodic table page contains isotope data for the element uranium

Naturally occurring uranium consists primarily of three isotopes (atoms with the same number of protons but a different number of neutrons).
