What varies in different isotopes of the same element? 🔊
What varies in different isotopes of the same element is the number of neutrons. Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons, leading to variations in atomic mass. This difference affects the stability of the isotopes, with some being stable and others being radioactive. The study of isotopes is crucial in fields such as chemistry, nuclear medicine, and archaeology.
