Isotopes of oxygen

Isotopes of oxygen are variants of the oxygen element that have the same number of protons (which is 8 for oxygen) but differ in the number of neutrons in their atomic nuclei. This difference in neutron number results in different atomic masses. The most common isotopes of oxygen are: 1. **Oxygen-16 (¹⁶O)**: This is the most abundant isotope, making up about 99.76% of natural oxygen.
