^{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 ...

On This Day in 1951, Four Illuminated Lightbulbs in Idaho Were Evidence of the First Time a Nuclear Power Plant Generated ElectricityAlthough it was just a byproduct of developing a new type of reactor, the generation of electricity from nuclear energy ...
Such a parent process could be a previous decay, or a nuclear reaction. For a summary table showing the number of stable and radioactive nuclides in each category, see radionuclide. There are 28 ...
Radioactive decay is a spontaneous and random process. A block of radioactive material will contain many trillions of nuclei and not all nuclei are likely to decay at the same time so it is ...
Example nuclear reactions include radioactive decay, fission, the break-up of a nucleus, and fusion, the merging of nuclei. In systematic studies of radioactive isotopes, the so-called islands of ...
They are created by nuclear fusion reactions in the sun, radioactive decay in nuclear reactors or the Earth's crust or in particle accelerator labs. As they travel, they can transition between one ...
The search for new elements comes from the dream of finding a variant that is sufficiently stable to be long-lived and not prone to immediate decay. There is a theory in nuclear physics about an ...
Some isotopes are stable, while others are radioactive and decay over time, emitting radiation. Carbon-14 is a radioactive isotope of carbon, meaning that it undergoes beta decay, releasing electrons.
A key isotope was produced from the decay of lawrencium atoms that were captured from a beam of nuclear reaction products and ...
