Uranium 238 is a natural isotope of uranium, non-fissionable with thermal neutrons, with an Atomic Mass of 238,050 788 247 ± 0,000 002 044 u.a. and a half life of 4,468 x 109 years, atomic number 92. Natural uranium contain 99.2745 % U 238 (atomic); the desintegration of U 238 is alpha type.
The decay product of uranium 238 by alpha disintegration (not beta or gamma) is thorium 234.
The approximate half life of Uranium 238 is 4.5 x 109 years.
The possible products of the alpha decay of uranium-238 are thorium-234 and helium-4. During alpha decay, the uranium nucleus releases an alpha particle (helium nucleus) and transforms into thorium-234.
uranium 238 is a fast neutron absorber the answer is correct but for more explanation:- when uranium 238 is bombard by neutron >>> uranium 238 , undergoes B decay>>>Np 239 ,undergoes B decay >>> Pu 239 finally undergoes alpha decay >>> fissile U
Uranium-235 and uranium-238 are two isotopes of uranium with different numbers of neutrons. Uranium-235 is used in nuclear reactors and weapons due to its ability to sustain a nuclear chain reaction, while uranium-238 is mainly used in depleted uranium ammunition and as a source of fuel for nuclear reactors. The main difference between the two isotopes is their nuclear properties and applications.
Plutonium 238 is an alpha emitter; the decay product is uranium 234.
The decay product of uranium 238 by alpha disintegration (not beta or gamma) is thorium 234.
The final product of the decay chain is the stable isotope 206Pb.
Plutonium 238 is an alpha emitter; the decay product is uranium 234.
Uranium-238 has 146 neutrons.
Uranium 238 is transformed in thorium 234 by alpha decay.
Uranium 238 has 146 neutrons.
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.
Uranium-235 and uranium-238 are isotopes of uranium, meaning they have the same number of protons but different numbers of neutrons. Uranium-235 is used in nuclear reactors and weapons due to its ability to sustain a nuclear chain reaction, while uranium-238 is more abundant in nature but less useful for these purposes.
Uranium-235 and uranium-238 are different isotopes of the element uranium. They have different mass numbers due to different numbers of neutrons.
Uranium 235 and uranium 238 are especially alpha particles emitters. They are natural radioactive isotopes.
In a uranium-238 atom, the number in the isotope name stands for the total number of protons and neutrons in the nucleus. So in this case, uranium-238 has 92 protons (atomic number) and 146 neutrons (238 - 92).
