The final product is a stable isotope.
Radon
Plutonium is a by product of nuclear reactions of uranium in a nuclear reactor. An example of reaction is: 23892U + n-------23992U-------23993Np + e--------23994Pu + e
You think probable to radon (radioactive gas).
esters
The reaction happens by itself.
Fermium is a product of nuclear reactions.
Radon
Helium
Plutonium is a by product of nuclear reactions of uranium in a nuclear reactor. An example of reaction is: 23892U + n-------23992U-------23993Np + e--------23994Pu + e
Rhenium :D
Now polonium is not obtained from natural sources; it is the product of some nuclear reactions.
You think probable to radon (radioactive gas).
A sequence of chemical reactions that lead from some precursor to a product, where the product of each step in the series is the starting material for the next step.
Natural francium is the decay product of actinium-227. Francium can be also obtained by nuclear reactions.
Natural francium is the decay product of actinium-227. Francium can be also obtained by nuclear reactions.
sun, fusion of hydrogen nuclei making helium nuclei (not radioactive)nuclear reactor, fission of uranium nuclei making a wide variety of different fission product isotopes having mass numbers from 72 to 161 (all very radioactive)
Reactions that increase the randomness. Reactions that have more moles of gas on the product side than the reactant side increase entropy. Also reactions that have a positive change in spontaneity and a negative enthalpy.
