There are many isotopes for uranium, the most abundant of them in nature are:

  • Uranium- 234, having 142 neutron and 92 proton
  • Uranium- 235, having 143 neutron and 92 proton
  • Uranium- 238, having 146 neutron and 92 proton
The abundance of these three isotopes in natural uranium is:
  • Uranium-234: 0.006 %
  • Uranium-235: 0.720 %
  • Uranium-238: 99.274 %

Can all types of uranium be used in making electricity in a reactor?

Uranium-235 and uranium-233 (obtained from thorium-232) are fissile isotopes and used as nuclear fuels. Uranium-238 is fissionable with fast neutrons but the important use is as fertile material (to obtain plutonium-239). Other uranium isotopes are without use.


What is the main use of isotopes of uranium?

235U is a fissionable isotope and 238U is a fertile isotope; these isotopes are extremely important in the production of nuclear energy. Also uranium is used by the United States, United Kingdom and Russia to threaten with nuclear bombs the other countries, without nuclear weapons.


How many isotopes uranium has?

Uranium has 3 natural isotopes (234, 235, 238) and 26 artificial isotopes.All the isotopes of uranium are radioactive.


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

Uranium isotopes


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.


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.


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.


Is uranium and plutonium the most common istopoes for nuclear power?

The most important isotopes for nuclear reactors are: - fissile isotopes: U-233, U-235, Pu-239, Pu-241 - fertile isotopes: Th-232, U-238


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 are uranium atoms?

Uranium has three natural isotopes and many artificial isotopes. Uranium 238 has 92 protons and electrons and also 146 neutrons.


Does uranium not have a stable isotope?

Uranium hasn't stable isotopes.


Is uranium naturally occurring or is it syntherically made?

Uranium has three natural isotopes: 234, 235 and 238; also uranium has ca. 25 artificial isotopes.
