Isotopes.
Isotopes, which are atoms of the same element with different numbers of neutrons.
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.
These atoms are called isotopes.
These atoms are called isotopes.
It's called an isotope.
