Each original isotope, called the parent, gradually decays to form a new isotope, called the daughter.

Each isotope is identified with what is called a ‘mass number’.

(The nucleus of an atom is made up of protons and neutrons.) For example, the element carbon, which always has six protons in its nucleus, has three isotopes: one with six neutrons in the nucleus, one with seven, and one with eight.

Some isotopes are stable, but some are unstable or radioactive.
