Stable Isotopes: Providing the Answers to Tough Questions

What is Stable Isotope Analysis? The different isotopes of an element have different numbers of neutrons (and therefore a different atomic mass). Many of the isotopic forms do not decay through time; hence the term 'stable isotope.'

Isotope Dating

First of all, lets review some basic facts: All of the atoms of a particular chemical element has the same number of protons in it nucleus. That is why they all have the same electron structure that controls their chemical properties.
