I think you mean Pu-239, but we'll look at both Pu-239 and Pu-238
We'll compare to aspects, the decay energy and the fissile energy.
First the decay energy.
U235 alpha decays and releases 4.679 MeV in the process
Pu238 alpha decays and releases 5.593 MeV
Pu239 alpha decays and releases 5.245 MeV
For the fissile energy.
U235 fissiling releases 202.5 MeV
Pu238 does not sustain a fissile, but the spontaneous fissile is 204.66 MeV
Pu239 fissilings releases 207.1 MeV
Pu238, because it does not sustain a fissile (though it does go through spontaneuos fissile) and because it does not emit much other stuff, other then the alpha particle, it works great as a nuclear battery.
For example 8 oz of Pu238 will power the average laptop for about 29 years, without ever needing to be recharged or replaced.
Nuclear fission of uranium-235 release fission energy.The fission energy is enormous compared to the energy obtained from fossil fuels.
The factors of 235 are 1, 5, 47, 235. For them to be common, they need to be compared to another set of factors.
Bombarding uranium-235 with _____ creates energy through fission.
A nuclear reactor is a facility which produce electricity and heat from the fission of uranium or plutonium.The energy released by fission of uranium-235 (or other isotopes) is immense compared to the energy content of fossil fuels.
The fission of uranium-235 nuclei
Uranium 235
The first three multiples of 235 are 235, 470 and 705. For them to be common, they need to be compared to another set of multiples. The first three common multiples of 2, 3 and 5 are 30, 60 and 90.
in some cases; its enriched uranium 235
Yes. For example, an atom of uranium-235 has stored energy (potential energy); after it splits, this is released, mainly as heat energy.
Thermal neutrons with an energy of 0,025 eV
From heat released when nuclei of uranium 235 undergo fission
In most nuclear plants this is uranium-235
