Uranium 235 and uranium 238 are isotope they are chemically different why?

I LIKE PIGS IN A BLANKET I think ,because when hit Uranium-238 by a neutron, it becomes uranium-239, an unstable isotope which returns into neptunium-239, which then itself decays, with a half-life of 2.355 days, into plutonium-239. ------------------------ Differences in nucleus stability and nuclear cross sections for fission with thermal neutrons.

∙ 15y agoShortly, the difference between naturally occurring isotopes of uranium are specially physical (Atomic Mass, neutron numbers, decay type, half life, etc). Also, U-235 is a fissile material with thermal neutrons in classic nuclear reactors and U-238 is the fissile material in a breeder reactor. They have different amounts of neutrons- U238 has 3 more than U235 and the neutrons control the chemical reactions of the atom.

Depleted uranium is chemically thee same as natural uranium but?
Has had most of the uranium-235 (an isotope of uranium)) separated out of it.
How is uranium 235 different from uranium 231?
Uranium-235 is a natural isotope with 143 neutrons. Uranium-231 is an artificial isotope with 139 neutrons.
What is a uranium atom?
Uranium atom has 92 protons and electrons; the number of neutrons is different for each isotope.
The isotope of uranium used in nuclear reactors uranium-235 contains 92 protons Another isotope uranium-238 contains how many electrons?
All the isotopes of uranium contains 92 protons and electrons but a different number of neutrons.
What does deutron bombardment of uranium isotope mean?
A nuclear reaction between an uranium isotope (e.g. uranium 238) and deuterons.

How is uranium 235 different from uranium 231?
Uranium-235 is a natural isotope with 143 neutrons. Uranium-231 is an artificial isotope with 139 neutrons.
Is Uranium Chemically Active?
No uranium is not chemically active
What is the uranium isotope with 144 neutrons?
There is no uranium isotope with 234 neutrons. The questioner almost certainly meant the uranium isotope with 234 nucleons, which is a naturally occurring isotope U234 otherwise element 92, with 142 neutrons.In which case its half life would be 252,000 years.

What is the atomic number of uranium and how many neutrons does the isotope uranium-235 have?
The atomic number of uranium is 92. The number of neutrons of the isotope uranium-235 is 143.
Is plutonium and enriched uranium the same thing?
Plutonium and enriched uranium are different materials.Enriched uranium is uranium with a concentration of the isotope 235U greater than the natural concentration of 0,7 %.
What is the percentage of uranium-235?
Uranium-235 is an isotope of uranium making up about 0.72% of natural uranium.
What is nuclear uranium?
Uranium-235 is the fissile isotope
What is the specific isotope of uranium?
Any isotope of uranium is specific. This notion don't exist.
