Isotope definition is any of two or more species of atoms of a chemical element with the same atomic number and nearly identical chemical behavior but with differing atomic mass or mass number and different physical properties.

Definition of isotope quizlet. Such measurements offer a powerful tool to interrogate a range of scientific problems from the origins of the terrestrial planets to past climate change to igneous processes and the. Looking at the percentages below each carbon isotope we see that almost 98 9 of the carbon that is found is in the form of carbon 12.
