Biology Exam Review Unit One – Biochemistry What is an isotope? Isotope - An isotope is all atoms of the same element that have the same number of protons‚ but they may have different numbers of neutrons in the nucleus. - This means that all atoms with the same atomic number can have different atomic masses. - Because they have the same number of protons and electrons‚ they behave exactly the same in chemical reactions.
