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.So that neutron basically emits an electron (the beta particle) and this essentially turns it into a proton. So we have to rely on something called radiometric dating to figure out the age of rock.Because these rates do not change and because the radiation that rocks give off can be measured, it became possible to calculate the time the rock was formed or, in other words, the rock's birth date - give or take a few thousand years or so.It's as if the nucleus is feeling too full of energy and it has to get rid of some, much like a hyperactive child who is so full of energy that he cannot stay seated in his chair.We call the unstable nuclide that undergoes radioactive decay the parent nuclide and the nuclide that results from the radioactive decay the daughter nuclide.But essentially, what is happening with beta decay is that we are taking a neutron, removing a negative charge and turning it 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.
