Concept radiometric dating

Each atom is named based on its number of protons, for instance, every atom that has only one proton is an atom of Hydrogen by definition.

In order to better understand atoms the concept of elements can be applied.

Elements provide a system of classification for all the different types of atoms.

Charge is a rationalization of how subatomic particles interact.

The rules are thus: opposite charges will attract and like charges will repel.

The principles of radioactive decay are clear and constant in every case.

A radioactive element emits some sort of particle or energy, and becomes a different element or isotope. A half-life is the time it takes for exactly one half of a sample to decay completely. It will take twelve years for one half of a sample of Tritium to decay, and it will take an additional twelve years for one half of the remaining sample to decay.

There are several different versions of each element with different numbers of neutrons; these are referred to as isotopes.

Atoms that don’t have the same number of electrons and protons are referred to as ions.

For instance, the most common isotope of Hydrogen contains one proton, no neutrons, and one electron.

This isotope is referred to as Protium because its nucleus consists of only one proton.

These isotopes are comparably stable, but Protium is far more abundant than Deuterium.
