Dating materials using radioactive isotopes updating wireless adaptor
When a gamma ray is emitted, the atomic nucleus releases energy, so we will see gamma decay taking place in a nucleus where the energy is too high.
The nucleus moves to a lower energy state by giving off this high-energy photon, and this allows the nucleus to reorganize itself into a more stable state. Radiometric dating, also known as radioactive dating, is what we use to determine the age of rocks.
When we talk about an alpha particle, we use the first letter of the Greek alphabet, which is here.
So let's zoom into a nucleus and take a look at this alpha decay process.
Specially defined isotopes, called nuclides, can be unstable and therefore undergo radioactive decay.So let's zoom into this nucleus and take a look at the beta decay process.Inside this nucleus, we see protons and neutrons, but let's say one of these neutrons is feeling as if things would be more stable if it could turn into a proton.A beta particle is shown with the Greek letter beta and is an electron that is emitted from the nucleus.Now, this might sound a bit odd to you, because you do not typically think about electrons being inside of a nucleus.
