What are isotopes?

Isotopes are different chemical element forms with the same atomic number but a different mass.

There are two isotopes of oxygen: oxygen-16 (also known as 16O, which is a "light" oxygen made up of 8 protons and 8 neutrons). The number of neutrons in the nuclei of oxygen-16 and oxygen-18 are different. While oxygen-18 contains 10 neutrons, oxygen-16 only has 8.
