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?

Uranium-235 and uranium-238 are isotopes of uranium, meaning they have the same number of protons but different numbers of neutrons. Uranium-235 is used in nuclear reactors and weapons due to its ability to sustain a nuclear chain reaction, while uranium-238 is more abundant in nature but less useful for these purposes.


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.


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.


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 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.


Two atoms of uranium that differ in their number of neutrons are called?

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.
