U from uranium235U and 238U (recommended); also possible U-235 and U-238 or uranium-235 and uranium-238.


Uranium-235 and uranium-238 are two different natural, radioactive isotopes of uranium.


Uranium 235 halflife: 7,038.108 years Uranium 238 halflife: 4,468.109 years


Uranium 235 and uranium 238 are especially alpha particles emitters. They are natural radioactive isotopes.


Uranium is a chemical element. Uranium has three natural isotopes (234, 235, 238) and 26 artificial isotopes.



The atomic number of uranium is 92, which means that all uranium atoms have 92 protons in their nuclei. They differ in the number of neutrons. Atoms of U-235 have 92 protons and 143 neutrons in their nuclei. Atoms of U-238 have 92 protons and 146 neutrons in their nuclei.


Uranium-238 don't suport a nuclear chain reaction; reasons belong to nuclear physics. Uranium-235 - yes !


Uranium-235 and uranium-238 are different isotopes of the element uranium. They have different mass numbers due to different numbers of neutrons.




Uranium-235 has 143 neutrons and uranium-238 has 146 neutrons. And of course the atomic masses are different.


Enriched uranium: uranium with more than 0.7 % uranium 235. Uranium 238 is not enriched uranium.


Uranium-238 (atom number 92) has 92 protons and the neutral atom has 92 electrons. This is also true for the other isotopes of uranium, eg. U-235.


Uranium has 92 electrons and protons.Uranium-234 has 142 neutrons, uranium-235 has 143 neutrons and uranium-238 has 146 neutrons.
