235 (mass number) - 92 (number of protons) = 143 (number of neutrons)
The atomic number of uranium is 92. The number of neutrons of the isotope uranium-235 is 143.
Uranium 235 is 0.7 percent of natural uranium and is fissile
Uranium-235 has 92 protons and 92 electrons. This is because the number of protons in an atom is equal to its atomic number, which is 92 for uranium. The number of electrons is also equal to the number of protons in a neutral atom.
Protons = 92 Electrons = 92 Neutrons = 146 The number of electrons and protons in a neutral atom are each equal to the atomic number of the element (92). The number of neutrons equals the atomic weight minus the number of protons (238 - 92 = 146).Uranium has 92 protons, 92 electrons, and usually 147 neutrons, though another isotope has 143 neutrons.
The atomic mass of uranium 238 is 238,050 788 247
Because the atomic mass of this isotope is approx. 235 atomic units of mass.
For example the isotope uranium-235 contain 92 protons and electrons, 143 neutrons.
A stable isotope of uranium-235 contains 143 neutrons.
The atomic number of uranium is 92. The number of neutrons of the isotope uranium-235 is 143.
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.
Uranium-235 is a natural isotope with 143 neutrons. Uranium-231 is an artificial isotope with 139 neutrons.
All the isotopes of uranium contains 92 protons and electrons but a different number of neutrons.
92 protons 92 electrons, 125 to 150 neutrons depending on the isotope (natural or artificial). For the natural isotopes of uranium: Uranium 238 has: 92 protons, 92 electrons and 146 neutrons. Uranium 235 has: 92 protons, 92 electrons and 143 neutrons. Uranium 234 has: 92 protons, 92 electrons and 142 neutrons.
Uranium-235 is an isotope of uranium making up about 0.72% of natural uranium.
After undergoing fission, the number of protons in the uranium-235 nucleus will remain the same. Uranium-235 has 92 protons, and fission does not change the number of protons in the nucleus.
The chemical symbol of uranium is U.
Uranium-235 is the fissile isotope
