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.
Has had most of the uranium-235 (an isotope of uranium)) separated out of it.
Uranium-235 is a natural isotope with 143 neutrons. Uranium-231 is an artificial isotope with 139 neutrons.
Uranium atom has 92 protons and electrons; the number of neutrons is different for each isotope.
Any isotope of uranium is specific. This notion don't exist.
The most common isotope of uranium is uranium-238.

Uranium-235 is a natural isotope with 143 neutrons. Uranium-231 is an artificial isotope with 139 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.
Uranium atom has 92 protons and electrons; the number of neutrons is different for each isotope.
Uranium-235 is an isotope of uranium making up about 0.72% of natural uranium.
Uranium-235 is the fissile isotope
Any isotope of uranium is specific. This notion don't exist.
The atomic number of uranium is 92. The number of neutrons of the isotope uranium-235 is 143.
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 %.
Uranium 235 is 0.7 percent of natural uranium and is fissile
The most common isotope of uranium is uranium-238.
Uranium has 92 protons and electrons; the number of neutrons is different for each isotope: number of neutrons = atomic mass of an isotope - atomic number of uranium (92)
