When the number of neutrons changes, the Atomic Mass will change.
The gram atomic mass, also known as molar mass, is the mass of one mole of an element or a compound in grams. It is numerically equal to the atomic or molecular weight of the substance in atomic mass units.
The mass does not change much. The Atomic number will increase though.
Atomic mass
The atomic mass (or weight) of silver is 107.8682 amu (atomic mass units)
The atomic mass number of aluminum is 27. The atomic mass of aluminum is 26.98115386
At first, he did it by atomic mass, but that didn't quite work out right, so he changed it to atomic number.

They are isotopes. They are the same element with a different amount of nuetrons, which can be determined depending upon the Atomic Mass and the atomic number, which results in the changed atomic mass.

The relative atomic mass was first proposed by John Dalton in 1803. According to it, the mass of an atom was expressed relative to the mass of one 1H atom. The unit was later changed to 1/16 of the mass of an oxygen atom. However, this measure was discarded when 17O and 18O were discovered. In 1961 the basic unit was changed (once again) to 1/12 of the mass of a 12C atom. The mass of any atom or molecule is measured in atomic mass units (AMU) and the units is defined as 1/12 the mass of a 12Carbon atom.

Mendeleev designed the periodic table by increasing atomic mass. But it was later changed to increasing atomic number.
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
