Radioactive decay
Radioactive decay is the process by which an atomic nucleus of an unstable atom . It loses energy by emitting ionizing particles. There are different types of radioactive decay. A decay, or loss of energy, results when an atom with one type of nucleus , called the parent "radionuclides" transforms to an atom with a nucleus in a different state, into a different nucleus containing different number of protons and neutrons.
Either of these products is named daughter nuclide. In some decays the parent and daughters are different chemical elements, and thus, the decay process results in nuclear transmutation.
Universal law for radioactive decay.
Radioactivity is one very frequent example for exponential decay. Thee law describes the statistical behavior of a large number of nuclides , rather than individual ones. In the following formalism, the number of nuclides or nuclide population N, is of course a discrete variable- but for any physical sample N is so large ( amts of
23
L=10 , Avogadro's constant) that it can be treated as a continuous variable.
