Isotopes exist because atoms of the

same element can have different numbers

of Different isotopes of the same element have different masses....

$\huge\underline\bold\pink{Explanation}$

Atoms of the same element, containing the same number of protons, but different numbers of neutrons, are known as isotopes. Isotopes of any given element all contain the same number of protons, so they have the same atomic number (for example, the atomic number of helium is always 2)..

The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. Different isotopes of the same element have different masses.
