143 & 146
The atomic number of uranium is 92. The number of neutrons of the isotope uranium-235 is 143.
A stable isotope of uranium-235 contains 143 neutrons.
143 neutrons
Uranium has 92 electrons and protons.Uranium-234 has 142 neutrons, uranium-235 has 143 neutrons and uranium-238 has 146 neutrons.
There are 143 neutrons.
Uranium-235 has 143 neutrons; uranium-238 has 146 neutrons. Each isotope has a different number of neutrons.
Uranium-235 is a natural isotope with 143 neutrons. Uranium-231 is an artificial isotope with 139 neutrons.
The main difference is in the number of neutrons present in the nucleus. Uranium-235 has 143 neutrons, while uranium-238 has 146 neutrons. This leads to differences in their relative abundance and stability.
The main difference between uranium-235 and uranium-238 is their atomic masses. Uranium-235 has 235 atomic mass units (AMU) while uranium-238 has 238 AMU. This difference in mass is due to the number of neutrons in the nucleus of each isotope.
Because the atomic mass of this isotope is approx. 235 atomic units of mass.
Uranium 235 has 92 protons and 92 electrons. To find the number of neutrons, follow this equation: Mass # - Atomic # = # of neutrons. Since the mass number of uranium 235 is 235 and has an atomic number of 92, the number of neutrons is 143.
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.
