Uranium is a metal. It undergoes many of the reactions common to metals, such as oxidation. Your question isn't very specific, so it's hard to give you a much better answer than that.
113 662.1016 uranium-234 atoms
Nuelceur Reactors amit radiation to the uraninaum that they they decay, spewing out and causing a chain reaction.
Uranium fission creates a chain reaction that initiates a chain reaction that grows exponentially into a massive conversion of the potential energy inside the uranium atom into kinetic energy in the form of an explosion - a nuclear explosion. These are the bombs that ended WW2. Today we can split H atoms, which release significantly more energy.
The most common isotope of uranium, 238U, has a poor cross-section (the ability to assimilate neutrons) for slow neutrons. In order to enhance the reaction, we enrich the uranium to 235U, from a natural level of about 0.7% to about 4%. This enhances the ability of the uranium to participate in a fissile reaction, i.e. one that sustains neutrons that fission atoms which creates neutrons, etc.
Uranium isotopes
Nuclear fission
Hahn, Meitner and Strassmann discovered the nuclear fission of uranium atoms in 1939.
In such a case nuclear fission occurs.
The answer is 15,2.1021 atoms of uranium.
156,86.1020 atoms of uranium in 6,2 g uranium

1 nanogram of natural uranium = 2,53.1012 atoms
Uranium atoms are split during nuclear fission. Uranium-235 and uranium-233 are fissile with thermal neutrons and uranium-238 is fissile with fast neutrons.

Uranium (as an element) has atoms, not molecules; uranium compounds are molecules.
