Uranium is a product mining, similar to other metals.
This depends on a lot of things. When a neutron collides with an uranium atom, it might bounce off, cause the atom to decay, or be captured into the atom. But which it does depends on the isotope of the atom, the temperature of the atom, and the velocity of the neutron. My understanding is that it can cause any isotope of uranium to decay, and certainly it can bounce off any, but it can only be captured by U233, U234, or U235; the other isotopes of uranium, U236, and U238, will not capture neutrons. The interactions of various isotopes of different temperatures with neutrons of different velocities is complicated, and no simple rule about it can be stated.
Examples:Oxides: uranium dioxide, uranium trioxide, uranium octaoxideSalts: ammonium diuranate, uranyl nitrate, uranyl acetate, uranium hehxafluoride, uranium chlorideand many others because uranium is a reactive metal.
The percentage of uranium in uranium dioxide is 88,149.
Uranium is delivered as oxides UO2 and U3O8, ammonium diuranate, uranium hexafluoride, uranium metal, uranium carbide.
We might think of induced nuclear fission as a fission reaction that occurs when a neutron is captured by, say, a uranium-235 atom and that atomic nucleus undergoes fission as a result. Most all of the fission events within a nuclear reactor or nuclear weapon are induced. Given this, we might then compare that fission event to a spontaneous fission event wherein the atomic nucleus of a uranium-235 atom spontaneously undergoes fission without having captured a neutron.
uranyl nitrate, uranium chloride, uranium tetrafluoride, uranium hexafluoride, uranium dioxide, uranium octaoxide, uranyl acetate, uranyl sulfate, uranyl oxalate, uranium carbide, uranium nitride, uranium sulfide, uranium sulfate, uranium selenide, etc.
The nuclear energy isn't so much as captured, but rather just "used". In the process, fission of uranium fuel rods causes water flowing through the reactor to be heated - eventually producing steam, which in turn spins turbines to create electricity.

Uranium is a chemical element with three natural isotopes (234, 235, 238). The natural uranium has cca. 0,72 % uranium-235; uranium with a concentration of uranium-235 under 0,72 % is called depleted uranium; uranium with a concentration of uranium -235 above 0,72 % is called enriched uranium. Uranium in nuclear power and research reactors is used as metal, aloys, uranium dioxide, uranium carbides, uranium silicides, etc.
Cold uranium is unirradiated uranium.
Uranium is delivered as oxides UO2 and U3O8, ammonium diuranate, uranium hexafluoride, uranium metal, uranium carbide.
Enriched uranium is an uranium with more than 0,7 % uranium 235.
