Inside this nucleus, we see the protons and neutrons.This parent nucleus is feeling somewhat unstable because it is too big or simply has too many protons, and it wants to get to a more stable state, so it's going to take two protons and two neutrons and kick them out of the nucleus as we see here.
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.
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.
So that neutron basically emits an electron (the beta particle) and this essentially turns it into a proton.
There is another type of decay that we want to learn about, but unlike alpha and beta decay, this type of decay does not release a particle.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.To better understand how radiometric dating helps us determine the age of rocks, it will help us to gain a better understanding of how elements decay.Radioactive decay is the term used for the process by which an unstable atomic nucleus loses energy by releasing radiation.Gamma rays can travel through your body but not through lead.
