Uranium 235 has 143 neutrons and uranium 238 has 146 neutrons.





Uranium-235 and uranium-238 has 92 protons and 92 electrons; but uranium-235 has 143 neutrons and uranium-238 has 146 neutrons.


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


The neutral atom of uranium (any isotope) has 92 electrons.



Uranium 235 has 92 neutrons and uranium 238 has 95 neutrons.


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


An isotope means an atom with the same amount of electrons and protons, but with different amount of neutrons.Relative weight of a neutron is 1, a proton is 1, and an electron is very small. So weight of an atom is approx. mneutrons + m protons.So, an uranium-235, as U is the 92th atom in periodic table, contains 92 protons, 92 electrons to be chargeless, and 143 (=235-92) neutrons.An uranium-238, from the definition of isotope, contains 92 protons, 92 electrons, and 146 (=238-92) neutrons.The difference is the 3 neutrons.



For an atom of uranium-235: 202,5 MeV.


Isotopes Uranium 235 and uranium 238 are only natural isotopes of the element uranium.


Uranium 234, 235 an 238 are all natural isotopes of uranium.Uranium 235- neutrons: 143- atomic mass: 235,043 929 918 ± 0,000 001 957- half life: 7,038.108 years- concentration in natural uranium: 0,7204 %- 235U is a fissile isotope


The atomic mass of uranium 235 is 235,043 929 918 ± 0,000 001 957.



During fission of uranium-235 with thermal neutrons the atom is splitted and many fission products are obtained.


Uranium-235 is a natural isotope with 143 neutrons. Uranium-231 is an artificial isotope with 139 neutrons.


when a neutron bombarded with 235 Uranium atom the atom become unstable which allow it to split and create two small atom and release more neutrons which can continue the reaction.


Uranium 235 has several isotopes but, 235 would contain 235 electrons in one atom.



Enrichment of uranium in the isotope uranium 235 is made by gaseous diffusion or by centrifugation.
