Depends, what do you mean "change"? Atomic Mass "changes" whenever something undergoes decay or breaks apart. In this respect, atomic mass is not exactly conserved either. Rest mass gets converted to energy; e=mc^2, meaning energy is equal to mass times the speed of light squared. This energy is usually the kinetic energy of the particle that gets dislocated from the original atom.

What is the atomic mass-?
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
The equation of atomic mass?
== The equation of atomic mass is protons+nuetrons== atomic mass. ===
What is the atomic mass of colbat?
Cobalt is an atomic mass of 58.93 atomic mass units
Is atomic mass unit a SI unit of an atomic mass?
The atomic mass unit is not a SI unit. An atomic mass unit is equal to 1/12 from the atomic mass of the isotope 12C.
What is the atomic no and atomic mass of graphite?
Atomic number 6, atomic mass 12.
Does atomic mass has a positive change?
No. Atomic mass is a measure of mass, not charge.
What changes in atomic number and mass number occur in beta emission?
Electron (beta minus) decay: the atomic mass remain approx. constant, the atomic number will be greater with 1 Positron (beta plus) and electron capture decay: the atomic mass remain approx. constant, the atomic number decrease with 1 Double beta decay: the atomic mass remain approx. constant, the atomic number will be greater with 2
Does the element change when the atomic mass changes?
yes the element changes when the atomic mass changes
Which of the following determines the identity of an element atomic number mass number atomic mass or overall change?
atomic number
What type of nuclear decay results in the atomic number increasing by one with no change in mass?
Beta- decay result in an increase of atomic number by one, with no resulting change in the atomic mass number.There is a change in mass, since an electron and an electron anti-neutrino is emitted, and also because the neutron changes into a proton, but the atomic mass number, per se, does not change.
What can be added or taken away from an atom to change the atomic mass?
Neutrons can be removed or added to change the atomic mass of an atom; a atom with the same amount of protons but different amounts of neutrons are called isotopes.(Taking or removing protons would change the type of atom and electrons do not have sufficient mass to change the atomic mass.)
When the atomic mass changes does the element change also?
no
How is the atomic mass changed?
When the number of neutrons changes, the atomic mass will change.
How does the atomic mass change when a proton is added to its nucleus?
Since the atomic mass consists of protons and neutrons, adding a proton would add one unit to the atomic massguessing that the number of neutrons doesn't change.
Does the atomic number changes when an ion is formed?
No, the atomic number does not change when an ion is formed. The number of protons does not change when an ion is formed, so the atomic mass would not change.
How did later chemists change Mendeleevs periodic table?
They used atomic number instead of Atomic Mass to organize the elements
Can the atomic mass of a particular element ever change?
yes
