Uranium metal has three allotropic forms:
And if you think to the isotopes, uranium has 3 natural isotopes: 234U, 235U,238U and ca. 24 artificial isotopes, all radioactive.
And if you think to enrichment (concentration of 235U) uranium may be: depleted, natural, low enriched, highly enriched.
Naturally occurring uranium is composed of three major isotopes, uranium-238 (99.2739 - 99.2752% natural abundance), uranium-235 (0.7198 - 0.7202%), and uranium-234 (0.0050 - 0.0059%).
The natural isotopes of uranium are U-234, U-235, U-238.
Uranium has also 26 artificial isotope and isomers.
14 stages; uranium-238 don't become stable - it is transformed in a stable isotope of lead.
See the link below for decay chains.
Alpha, beta and gamma decays
Isotopes Uranium 235 and uranium 238 are only natural isotopes of the element uranium.
Isotopes are atoms of the same element but with a different number of neutrons.Example for the isotope 228 of uranium:- uranium-228- U-228-- 22892U
Yes.......most likely. I can't think of anything to do with Uranium, that isn't radioactive! -------- Uranium natural isotopes are not so radioactive compared with other isotopes; but all the isotopes of uranium are radioactive.
No, Uranium-235 and uranium-238 are radioactive, natural isotopes (not molecules, but atoms) of the one and the same element: uranium.Both with 92 protons and 235-92 = 143 neutrons in U-235 but 146 neutrons in U-238.
Ultimately lead, as it is the only element in the uranium decay chains with isotopes that are stable. Specifically the isotopes 206, 207, and 208; each of which is the end of a different decay chain.
Isotopes Uranium 235 and uranium 238 are only natural isotopes of the element uranium.
Uranium-235 and uranium-238 are different isotopes of the element uranium. They have different mass numbers due to different numbers of neutrons.
No, only the number of neutrons is different.

Uranium-235 has 143 neutrons and uranium-238 has 146 neutrons. And of course the atomic masses are different.
All the isotopes of uranium are unstable.Natural isotopes of uranium are: 234, 235 and 238.
20 isotopes
Uranium has a number of isotopes including U235 and U238, both of which are radioactive
