The stability depend on the ratio between protons and neutrons; uranium has too many neutrons.
The energy is stored in the atoms - in the forces between protons and neutrons - from the start, as a type of potential energy.
An atom "becomes" radioactive when it is created. It's that simple. Radioactivity is a phenomenon associated with atoms that have unstable nuclei. The key is that the protons and neutrons that form the nucleus "don't like" the "arrangement" there and the atomic nucleus is unstable. The "ratio" of protons to neutrons in a nucleus is intrinsically unstable. The instability is something that the nucleus, when it is formed (and by whatever means), has as an innate quality. It is unstable, and it isradioactive, and at some point in time, it will undergo decay, or even spontaneous fission, in the case of certain atoms, like uranium and plutonium.
artificial radioactivity is carried in synthetically produced radioactive elements used in nuclear reactors and accelerators whereas natural radioactivity is a spontaneous process of disintegration of nucleolus of an atom. This process occurs in elements having atomic number greater than 83
Protons repel each other electrically. However, there is another force that counteracts that: the strong force (or "residual strong force") that acts between nucleons (protons and neutrons). Note that two protons alone can't stick together; but if there are also a few neutrons, the strong force becomes dominant.Protons repel each other electrically.

The atom is unstable.
Radioactive substances are unstable as a result of the extra neutrons present in the nuclei of the substance. Non radioactive substances are stable.

Chemically there is no difference between radioactive nitrogen and stable nitrogen. Both will react the exact same way in all chemical reactions. The only difference between the two is the number of neutrons in the nucleus. This means the only difference is mass. If the nitrogen atom has too many neutrons, it will most likely give off a beta particle. The beta particle shoots out from one of its neutrons. That neutron then becomes a proton and the nitrogen becomes oxygen. If the nitrogen atom has too few neutrons, a proton in its nucleus may capture one of its own electrons and turn into a neutron. This would then turn the nitrogen atom into a carbon atom.
Whether an ISOTOPE (not element) is naturally radioactive depends not only on the number of protons, but also on the number of neutrons. For EVERY element, there are radioactive isotopes.There has to be a certain relationship between the number of protons and the number of neutrons, but the relationship isn't a simple one.

Yes. The Strong Nuclear Force is the force that holds the protons and neutrons together in the nucleus and is transmitted by gluons. It is the glue that holds the nucleus together. The Weak Force is responsible for the decay of radioactive elements. It ejects neutrons from the nucleus of a radioactive atom.
In most atoms the protons and neutrons found in the nucleus are held together strongly. The nuclei of these atoms are said to be stable. However, the neutrons and protons in some atoms are not held together as strongly. These nuclei are unstable and will eventually disintegrate, forming other elements. Isotopes that are unstable are said to be radioactive and are called radioactive isotopes or radioisotopes.

An isotope of a chemical element is an atom that has the same number of protons (this also means this atom has the same atomic number) and electrons, but has a different numbers on neutrons. The isotope is radioactive if it has too many neutrons in the nucleus and because of this the isotope is unstable. The half-life of a radioactive isotope is a time period. When the isotope is at the end of the period it's weight will be the half of the starter weight.
Carbon comes in 3 varieties called isotopes, which have different numbers of neutrons. The vast majority of carbon is carbon-12, which has 6 protons and 6 neutrons (all carbon atoms have 6 protons, that's what makes it carbon). Less common is carbon-13, which has 6 protons and 7 neutrons. The rarest is carbon-14, which has 6 protons and 8 neutrons. It is mildly radioactive.
