Pu-239 has a half-life of 24,110 years.
the halflife is 10 days
The half life of 238U is 4,468.109 years; this is a very long halflife !
Most uranium is U-238, with has a very long halflife. Bombard it with neutrons (fast breeder reactor) to make plutonium-239, which is a suitable fuel for a fission reactor. Lift it up high, and tie a rope to it. As it falls, have it drive a generator. Same scenario, only drop it into a black hole... get lots more energy.
Uranium is used as the feed fuel in nuclear power plants. Natural uranium contains 0.7 percent U235 but this is increased to about 4 percent for light water moderated reactors. The bulk of uranium is U238 and this is not productive, though some of it turns to plutonium during operation and this gives further energy output. The reaction with U235 and Pu239 is called fission, whereby the nucleus splits into two parts and releases energy
Nuclear fusion produces energy because the binding energy of the nucleons in the resulting nucleus is greater than in the starting nuclei. The same happens when a heavy nucleus, U235 or Pu239 for example, splits up. These are both examples of nuclear energy, but as we have not yet learned how to use fusion for power production, useful nuclear energy on earth is only available from fission.

Yes.
which process & which isotope u mention 1. nuclear reaction U235 & Pu239
yes
Enough of either U235 or PU239 to form a critical mass and hence a large explosion
U-238 --> alpha + gamma + Th-234, halflife 4.51E9 yearsTh-234 --> beta- + gamma + Pa-234, halflife 24.10 daysPa-234 --> beta- + gamma + U-234, halflife 6.66 hours
The logo has a border, however the lambda is in the center.
Yes, but it has a halflife of only 0.86 seconds.
The half-life of carbon-11 is 20.334 minutes.
