Uranium-238 (238U or U-238) is the most common isotope of uranium found in nature. It is not fissile, but is a fertile material: it can capture a slow neutron and after two beta decays become fissile plutonium-239. 238U is fissionable by fast neutrons, but cannot support a chain reaction because inelastic scattering reduces neutron energy below the range where fast fission is probable.

Uranium 235, which alone constitutes 0.72% of natural uranium is the second common isotope of uranium in the nature. This isotope has half-life of 7.04×10 8 years (6.5 times shorter than the isotope 238) and therefore its abundance is lower than 238 U (99.28%).

The actual difference is that one has 235 protons in the nucleus and the other has 238. If you dig up a uranium rock it will be 99% u238 and only 1% u235.

The isotopes are separated by forming uranium hexafluoride UF_6, which is a gas, then allowing it to diffuse through a series of porous membranes. 235UF_6 has a slightly larger rms speed than 238UF_6 and diffuses slightly faster. Uranium-235 (U-235) Half-life: 700 million years. Uranium-238 (U-238) Half-life: 4.47 billion years.

2018-04-04 2 days ago Common fissionable isotopes are 232 Th and 238 U, and the subset of fissile materials including 233 U, 235 U, and 239 Pu. Fig. 6.3 compares the fission cross-sections for fissile 235 U and 239 Pu to that of 238 U, which has a σ f that is more than seven orders of magnitude smaller at Uranium 235. Uranium 235, which alone constitutes 0.72% of natural uranium is the second common isotope of uranium in the nature. This isotope has half-life of 7.04×10 8 years (6.5 times shorter than the isotope 238) and therefore its abundance is lower than 238 U (99.28%). 235 U belongs to primordial nuclides, because its half-life is comparable to the age of the Earth (~4.5×10 9 years). 238 U. 238 U decays via alpha decay to 234 Th with half-life of ~4.5×10 9 years.

U-235 is fissile, which means that slow-moving neutrons can cause fission. U-238 is fissionable, which means that only fast, energetic neutrons can cause fission Główna różnica - U 235 vs U 238 Pierwiastki radioaktywne to związki, które rozkładają się z czasem, uwalniając energię i zamieniając się w różne elementy. Dzieje się tak, ponieważ te elementy nie są stabilne. The water drop model of an atom’s nucleus explains it well. First, two protons don’t want to be right next to each other due to electric repulsion. But if they get very close, there’s an extremely short range force that will hold them together, bu Unterschied zwischen U 235 und U 238 Definition.
