How does the nucleus of an atom change after a gamma radiation? The atomic mass reduces by four and the atomic number reduces by two
The atomic mass remains the same, but the atomic number increases by one.
The atomic mass changes by one, but the atomic number remains the same,
Od
The atomic mass remains the same, but energy is lost as the nucleus decays.
