Isotopes have a different amount of Neutrons. The Atomic Mass is the sum of Protons and Neutrons. Therefore having a different number of Neutrons makes the atomic mass greater. Or vice versa. Boom. Solved.
The atomic mass of an element is the average of its isotopes, weighted by abundance in nature.

The atomic mass of an element is the average of its isotopes, weighted by abundance in nature.
The atomic weight of an element is a number that takes into account the natural distribution of the isotopes of that element.
The atomic number is the same for the all isotopes of a chemical element.
Yes; isotopes of the same element have the same atomic number but differ in their atomic masses.
Isotopes contribute to the atomic weight of a chemical element.

the Atomic Mass
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).
Isotopes contribute to the atomic weight of a chemical 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).
The atomic weight of an element is derived from the atomic masses of the isotopes of this element and from the percentage of these isotopes. The correct terms are: - atomic weight for elements - atomic mass for an isotope
Atomic mass number is the average atomic mass for that element, which is : All the isotopes' masses known for that element averaged up. Atomic number is the element's "identity", the number of protons the element and all its isotopes have. All the isotopes of a given element will have different number of electrons and neutrons, but the protons of the element never will change.
The known weighted-averagemass of all the naturally occurring* isotopes for an element is the atomic mass of the element.____________________*This is not the same as "all the known isotopes", becausemost elements have known isotopes that are not naturally occurring.
