The atomic number is the same for the all isotopes of a chemical element.
Yes, isotopes of an element have the same number of protons but different numbers of neutrons, leading to variations in atomic mass. This is why the atomic mass on the periodic table is often listed as a range for an element.
They are called isotopes. They have different mass nmbers because they have a different number of neutrons.
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.

We call these different "flavors" of an element the isotopes of that element.

Atoms of the same element with different atomic masses are known as isotopes. Isotopes differ only by the number of neutrons present in the nucleus of the isotopes. The number of protons is the same for all isotopes of an element (because if there were different numbers of protons, then the atoms would not be of the same element).

atomic masses
Different isotopes of an element differ in the number of neutrons and thus in their atomic weight.
We call these different "flavors" of an element the isotopes of that element.
Isotopes of the same element have different numbers of neutrons in their atomic nuclei. This results in isotopes having slightly different atomic masses while maintaining the same number of protons (which determines the element's identity).
All isotopes of an element have the same number of protons in the atomic nucleus, which is its atomic number on the periodic table. All isotopes of an element contain different numbers of neutrons in their atomic nuclei, which causes the isotopes of an element to vary in mass number (protons + neutrons).
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.
