Atoms of the same element that have different masses are called isotopes. Different masses result when there are different numbers of neutrons. All atoms of a particular element have the same number of protons. To identify the different isotopes of an element, the element symbol is written followed ...

Atoms of the same element can have different numbers of neutrons; the different possible versions of each element are called isotopes. For example, the most common isotope of hydrogen has no neutrons at all; there's also a hydrogen isotope called deuterium, with one neutron, and another, tritium, with two neutrons.

If you’re talking about the same element like hydrogen but with different number of neutrons then it is called an isotope like protium(0), deuterium(1), tritium(2) If you’re talking about different elements with same neutron number then they are isotones, like Boron B12(7) and Carbon C13(7) both have same number of neutrons

Atoms of the same element always have the same number of protons ( is it had a different number of protons it would be a different element). However atoms of the same element can have different numbers of neutrons (this gives them a different mass number). Different versions of the same element are called isotopes.
