A report about the decay and half-life of different radioactive elements. It is impossible to predict when any one atom will decay but by looking at a number of atoms an average rate of decay can ...

Radioactive decay is a stochastic (i.e. random) process at the level of single atoms. According to quantum theory, it is impossible to predict when a particular atom will decay, regardless of how long ...

^{4}\textrm{He}\) When a radioactive atom emits an alpha particle the mass number decreases by four and the atomic number drops by two. Here is the equation for the alpha decay of radon-219 into ...

Try to keep the same number of neutrons and protons as you build your atom. If the imbalance is too great, radioactive decay will occur. Up to two electrons may exist in the atom's first shell.

This detector registered their implantation as well as their subsequent decay. In total, 27 atoms of Rf-252 decaying by fission with a half-life of 13 microseconds were detected. Thanks to the ...
