No, uranium is not the only element that can be used in nuclear fission. Other elements like plutonium and thorium can also undergo nuclear fission reactions. Uranium-235 is the most commonly used isotope, but plutonium-239 and thorium-232 can also sustain fission reactions in certain nuclear reactors.
Uranium is the only naturally occurring element used for nuclear fission in commercial nuclear reactors. It is typically found in two isotopes, uranium-235 and uranium-238, with uranium-235 being the primary isotope used for nuclear fission reactions.
Uranium itself does not blast or explode on its own. It can undergo a process called nuclear fission in a controlled environment such as a nuclear reactor, leading to a highly energetic chain reaction. Uncontrolled fission could result in a nuclear explosion.
Nuclear fission happens spontaneously in nature. Uranium-235 does this, and is the only commonly occurring natural isotope that does. Nuclear fission can be induced by crashing a neutron into a fissionable atom. Some things other than Uranium-235 are fissionable, notably Uranium-238. Fission has been induced in various experiments. It happens in nuclear reactors and in nuclear bombs.
Uranium is fairly easy to obtain, and the 235 isotope can be separated or increased, which is the fissile one. The only alternative is plutonium, and that has to be separated out from used uranium fuel. In some countries, but not the US, this has been done and a mixed uranium/plutonium fuel produced.
Because uranium-235 can easily be made to fission in a reactor with a moderator to slow the neutrons down, a chain reaction can be sustained, and heat is generated which can be harnessed for electricity. Uranium is usually used because it is the largest naturally occurring atom. A smaller atom would not split as easily, and a larger atom would first need to be created before it could be split.Also Uranium-235 is the only isotope capable of undergoing fission and supporting a chain reaction of any element on earth that occurs naturally at high enough levels (0.72% of natural Uranium) to make it economically extractable. Other fissionable materials have to be produced in sufficient quantities in "breeder reactors" where the radiation converts certain non-fissionable elements into other fissionable elements through neutron capture. Because uranium is much more common that was believed early in the development of nuclear reactors, it is much more economical to refine naturally occurring uranium (separating the U-235 from U238) than to use breeder reactors to convert non-fissionable isotopes into fissionable ones and then refine the result to produce more nuclear fuel.A very slightly different world (e.g. older) and nuclear energy and weapons might never have been possible at all.

uraniumThe only natural element currently used for nuclear fission in reactors is uranium. Natural uranium is a highly energetic substance: one kilogram of it can generate as much energy as 10 tonnes of oil

In fission reactors, which is the only practicable source of energy at present, it is the fission of the nuclei of uranium and plutonium which produces the energy
It was not a specific sort of atom. They split the atom.Not only is it a specific atom (element), it is a specific isotope of that element: Uranium-235. This is the one and only naturally occurring isotope that fissions and supports a chain reaction.

The only alternative is plutonium, and that has to be separated out from used uranium fuel. In some countries, but not the US, this has been done and a mixed uranium/plutonium fuel produced.
Fission in Uranium would take billions of years when its left to its own devices. Because of radioactive decay, it would either release alpha or beta radiation, or fission. The earth would have to be really old for that to maybe happen. Besides, Only less than 1% of Uranium is U-235, which is the only isotope of uranium that would fission, is found on earth.

Nuclear fission reactions primarily produce two main elements: fission fragments (such as cesium, strontium, and xenon) and neutrons. These fission fragments can further undergo radioactive decay and produce additional elements.
No, since uranium in a radioactive element, it stores Nuclear energy.Actually metallic uranium stores lots of chemical energy and can burn violently. Finely divided metallic uranium is even pyrophoric (it will ignite on exposure to air).
Yes U235 is the fissionable isotope of Uranium. Natural Uranium contains only about 0.7 percent U235, which is enough to produce fission only with a good moderator such as graphite or heavy water. In light water reactors the Uranium has to be enriched to about 4 percent U 235.
