We need the isotope uranium-235 in a concentration near to 99 % ! Only this isotope is fissile. Also the uranium will be very pure and in a sufficient quantity to form the critical mass, etc.
Radon is a radioactive chemical element that is created through the natural radioactive decay of uranium. Since uranium occurs naturally throughout our planet, we also find radon naturally.
URANIUM (:
There are many isotopes, especially of the trans-Uranium elements which can undergo nuclear fission. The isotopes which are used in nuclear reactors are Uranium-233, Uranium-235 and Plutonium-239, because these isotopes are more readily available than other fissionable isotopes. Uranium-235 occurs naturally, Uranium-233 can be made by neutron irradiation of Thorium-232 and Plutonium-239 can be made by neutron irradiation of Uranium-238.
Its called fission.
False!! Because we can help change the ecosystem in our ifes in nature
Radon is a radioactive chemical element that is created through the natural radioactive decay of uranium. Since uranium occurs naturally throughout our planet, we also find radon naturally.
In such a case nuclear fission occurs.

corruption occurs because it is human nature to take the easy way out
Radon comes from the soil. It occurs naturally from decaying uranium.
The metal most commonly used is enriched uranium, meaning that it has a higher percentage of uranium-235 than occurs in nature. Plutonium is also used in some reactors, in combination with uranium. And thorium can also be used, though research on its use has only just begun. Usually it is not the metal that is used in any case, but a compound of the metal. There is a link below.
Uranium because uranium has the highest atomic number, 92, of the natural, actinide elements. Elements higher than 92 are man-made elements. Check the periodic tables to see for yourself!~
No, gay people are not unnatural. Consider the following points:If something occurs in nature, then it's natural.Homosexuality occurs in nature.Just because something doesn't occur in nature, does not mean we shouldn't do it. Writing doesn't occur in nature. Football doesn't occur in nature. Hearing aids don't occur in nature.
Yes it comes from the soil. It occurs naturally from decaying uranium.
