The different isotopes have different Atomic Mass numbers, because the isotope has different numbers of neutrons. The protons and electrons are the same, so the change in mass number is the same as the change in the number of neutrons.

Can isotopes of an element have the same number of neutrons?

Two different isotopes of an element have different numbers of neutrons. That's what an isotope is. So, no, isotopes of an element can not have the same number of neutrons.


Compare the atomic numbers of isotopes to mass number of the same element?

The atomic number of isotopes of the same element is the same because they all have the same number of protons in their nucleus. The mass number of isotopes, however, can vary because it is the sum of protons and neutrons in the nucleus, and different isotopes can have different numbers of neutrons.
