Solution

The correct option is C

Does not change


The atomic mass does not change with chemical change. The loss or gain of electrons does not change the atomic mass because the mass of electrons is much lighter than nucleons. The mass of electrons is not considered for atomic mass. Atomic mass depends upon protons and neutrons.
