An isotope is a variant of a chemical element that has the same number of protons in its nucleus, but a different number of neutrons. This results in different atomic weights and slightly different physical properties.
- Isotopes of an element have the same number of protons, meaning they belong to the same element on the periodic table
- Isotopes have different numbers of neutrons, resulting in variations in atomic mass
- Some isotopes are stable and do not undergo radioactive decay, while others are unstable and decay over time
- Isotopes are commonly used in radiometric dating, medical imaging, and nuclear energy production
- The study of isotopes is important in geology, chemistry, and biology for understanding processes such as the formation of rocks, chemical reactions, and biological processes
