Yes. Isotopes have the same atomic number because all of their atoms have the same number of protons. They have different mass numbers because their atoms have different numbers of neutrons, and mass number is the sum of the numbers of protons and neutrons.
If they have the same atomic number but different mass, then they have a different number of neutrons, and they are called ISOTOPES.

Two atoms are isotopes if they have the same number of protons but different numbers of neutrons in their atomic nuclei. This results in atoms of the same element having different atomic masses.
Yes; isotopes of the same element have the same atomic number but differ in their atomic masses.
Atoms that have the same atomic number but different neutron numbers are known as isotopes. Isotopes of an element have the same number of protons but different numbers of neutrons, leading to variations in their atomic mass.
No. Isotopes have the same atomic number, protons and electrons. They have different neutrons.
The atomic number of the isotopes of an element is identical; the mass number is different.
No. By definition isotopes of an element have the same number of protons (that is what makes them uranium, for example) but different numbers of neutrons (neutral particules in the nucleus which provide mass).
The different mass numbers are due to different numbers of neutrons.
Isotopes are atoms of the same element with the same number of protons but different numbers of neutrons. This results in isotopes having the same atomic number but different atomic masses.
Isotopes of an element have nuclei with the same number of protons (the same atomic number) but different numbers of neutrons Neutrons (:
The isotopes of an element must have a different amount of neutrons. I'm pretty sure you know what these are, but just in case: A neutron is a sub-atomic part of an atom, together with protons and electrons.
