Uranium metal has three allotropic forms:
- α (orthorhombic) stable up to 660 °C
- β (tetragonal) stable from 660 °C to 760 °C
- γ (body-centered cubic) from 760 °C to melting point-this is the most malleable and ductile state.
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.

Uranium -235 and uranium -238 are different of uranium?
Isotopes Uranium 235 and uranium 238 are only natural isotopes of the element uranium.
What are isotopes and how do you label them?
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
What isotope uranium is radioactive?
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.
Are uranium 235 and uranium 238 said to be radioactive molecules since they have the same number of protons but different numbers of neutrons?
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.
What isotopes accumulate in old uranium-bearing rock?
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.
Uranium -235 and uranium -238 are different of uranium?
Isotopes Uranium 235 and uranium 238 are only natural isotopes of the element uranium.
Uranium-235 and uranium-238 are different?
Uranium-235 and uranium-238 are different isotopes of the element uranium. They have different mass numbers due to different numbers of neutrons.
Does isotopes of uranium have different number of electrons?
No, only the number of neutrons is different.
What are isotopes and how do you label them?
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
How many isotopes uranium has?
Uranium has 3 natural isotopes (234, 235, 238) and 26 artificial isotopes.All the isotopes of uranium are radioactive.

What are the similarities and differences between the isotopes uranium 235 and uranium 238?
Uranium-235 has 143 neutrons and uranium-238 has 146 neutrons. And of course the atomic masses are different.
Is the isotope of uranium you found in a stable r radioactive?
All the isotopes of uranium are unstable.Natural isotopes of uranium are: 234, 235 and 238.
How many different elements appear in the uranium-238 decay series?
20 isotopes
Isotopes of elements?
Uranium has a number of isotopes including U235 and U238, both of which are radioactive
