Atoms of the same element that differ in mass number are called isotopes since all atoms of a given element have the same number of protons in their. Radioactive decay results in a reduction of summed rest mass, once the released energy (the disintegration energy) has escaped in some way although decay energy is sometimes defined as associated with the difference between the mass of the parent nuclide products and the mass of the decay products, this is true only of rest mass measurements, where some energy has been removed from the product system.
