They have the same number of protons, but different numbers of neutrons. Because neutrons have no charge in the atom structure, there can be more or less of them without making a difference in the atom, except in the mass.

Isotopes of an element have the same number of protons but different numbers of neutrons. Just for the record: The number of protons determines the element.. The number of neutrons determines the isotope of the element. The number of electrons determines the ion of the element.

To take an example that may help you to remember this, deuterium and tritium are isotopes of hydrogen, differing in that they have 1 and 2 neutons in the nucleus respectively, whereas everyday hydrogen has none. When combined with oxygen, they make heavy water and super-heavy water. All of the hydrogen isotopes have just one proton. So the answer is your first alternative, "protons" and "neutrons".
