WebThis means that the atom's nucleus has 27 protons (this is makes it cobalt) and 32 neutrons (for a total mass of 27 + 32 = 59). If you expose the Co-59 to neutron radiation, then the nucleus may absorb a neutron. If it does, it will now have 33 neutrons, and be called Cobalt-60. Co-60 is very radioactive. You have taken a thing that was stable ... WebRadioactive atoms have unstable nuclei, and they will eventually release subatomic particles to become more stable, giving off energy—radiation—in the process. Often, elements come in both radioactive and nonradioactive versions that differ in the number of neutrons they … An atom is the smallest unit of matter that retains all of the chemical properties o… If there are too few or too many neutrons, the nucleus won't be stable. The details … WebNov 25, 2024 · I can see how neutrons are able to do this with "induced radioactivity" although I don't quite understand if the metal has transmuted or just briefly unstable.

WebRadioactive decay is a natural process and comes from the atomic nucleus becoming unstable and releasing bits and pieces. These are released as radioactive particles (there are many types). This decay process leads to a more balanced nucleus and when the number of protons and neutrons balance, the atom becomes stable. WebThis means that it is barely radioactive, less so than many other isotopes in rocks and sand. Nevertheless it generates 0.1 watts/tonne as decay heat and this is enough to warm the Earth's core.
