Dating materials using radioactive isotopes ryan sypek genevieve cortese dating real life
We call the unstable nuclide that undergoes radioactive decay the parent nuclide and the nuclide that results from the radioactive decay the daughter nuclide.
This is a fairly easy concept to remember because it is as if the original nuclide is giving birth to the new nuclide, much like a human parent and daughter relationship.

Radiometric dating is a method used to date rocks based on the known decay rate of radioactive isotopes. Now, they do not give off enough radiation that you have to be afraid to pick them up, but they do contain naturally occurring radioactive elements like uranium, for example.
So let's zoom into a nucleus and take a look at this alpha decay process.
So with this decay, we do not see the number of protons or neutrons within a nucleus changing. This decay is called gamma decay, and it is denoted by the third letter of the Greek alphabet, gamma, which looks like a lowercase 'y.' We define gamma decay as a type of radioactive decay where a gamma ray is emitted.
A gamma ray is a high-energy photon, and you have experienced gamma rays if you ever had an x-ray taken.
If we have a parent nucleus where the neutron-to-proton ratio is too great, then that parent might be feeling unstable about its circumstance and want to move to a more stable state through beta decay.
Beta decay is a type of radioactive decay where a beta particle is emitted.

We know that elements can exist as isotopes, which means that their atomic nuclei contain the same number of protons but different numbers of neutrons.
