Imagine we have an undiscovered element, Parentium, that has a radioactive isotope, Parentium-123, which decays to stable Daughterium-123.This is the only way Parentium-123 decays, and there is no other source of Daughterium-123.But there are some questions that come to mind: Calculus students typically meet this problem somewhere in the second semester.It is one of the simplest examples of a differential equation.Two situations where we can do this involve Potassium-40 atoms and Carbon-14 atoms.All radioactive atoms decay to become a more stable kind of atom.The nucleus contains protons (tiny particles each with a single positive electric charge) and neutrons (particles without any electric charge).Orbiting around the nucleus are electrons (tiny particles each with a single electric charge).
This predictability allows scientists to measure the age of an object if they can work out how many radioactive atoms were originally present.
The atoms in each chemical element may vary slightly in the numbers of neutrons within their nuclei.
These slightly different atoms of the same chemical element are called isotopes of that element.
This is an enormous branch of geochemistry called Geochronology.
It is an accurate way to date specific geologic events.
We could be sure that a mineral containing parentium originally had no daughterium.
