ISOTOPESAn ISOTOPE is an atom that has missing neutrons or extras neutrons. An atom is still the same element if it is missing a neutron. They are just a little different from every other atom of the same element. Take carbon for example:There are a lot of carbon atoms in the universe. The normal ones are carbon-12. These atoms have 6 neutrons. There are a few straggler atoms that don't have 6. Those odd ones may have 7 or even 8 neutrons. As you learn more chemistry, you will probably hear about carbon-14. Carbon-14 actually has 8 neutrons (2 extra). C-14 is considered an isotope of the element carbon.
