Solution

Neutrons.

Isotopes are defined as the atoms of the same element, having the same atomic number but different mass numbers.

Since,

mass number = number of protons + number of neutrons

the number of protons in all the atoms of a particular element is same, therefore to have different mass numbers, isotopes contain different number of neutrons.
