The underlying truth in radioactive decay is that on an individual basis, no unstable atom will have a predictable time until it will decay. We understand and characterize the decay of radionuclides on the basis of statistical analysis. Only by looking at a large number of atoms of a given isotope of a given element and counting the decay events over time can we quantify the decay rate. The term half-life is used to state (based on the statistics) when half of a given quantity of a substance will have undergone radioactive decay. Note that atoms are incredibly tiny things, and even if we have very tiny quantities of a given radioactive material, we'll have huge numbers of atoms of that material in the sample. The larger the number of atoms of material and the longer we count the decay events, the more accurate our half-life value will be. Having said all that, no one can predict when a given atom of any radionuclide will decay. Each is different, and that is the basis for the random nature of nuclear or radioactive decay.
It is impossible to predict when a nucleus will decay and by what type of emission will it decay. Also the probability of a nucleus decaying is the same for all nucleuses in a given sample.
Atomic nuclei that are unstable and decaying are said to be radioactive. Radioactive decay involves alpha, beta and gamma particle emissions.
Radioactive decay may or may not involve electrons. There are different types of radioactive decay.
It is through radioactive decay that a quantity of an unstable element will decay over time. A material that is unstable will undergo this process, and the sample is said to be radioactive.
when an isotope is it does not undergo radioactive decay
They experience radioactive decay. They emit radiation, changing the state of their nucleus, usually by the loss of protons and neutrons. However, this process is completely random; it can only be predicted as a half-life, or the amount of time it takes half of a certain material to decay. This does not predict when an individual atom will decay, it only predicts when approximately half of the material will have decayed.

Radioactivity, and more specifically, radioactive decay, involves the spontaneous expulsion of a proton from the nucleus of an atom. It is important to note that this process is random and spontaneous; in other words, we can never know exactly when an element will decay.

The radioactive decay of americium 241 is by alpha disintegration; the disintegration of radioactive krypton isotopes is by beta particles emission.
