How does the total mass before a nuclear reaction compare with the total mass after a nuclear reaction?

Atomically speaking, there is a small mass defect between the parent molecule and the one “achieved” after the reaction. This small amount lost is actually the energy converted and from the matter through the reaction and released as a by-product; when observed on the macro scale, this small amount of material lost results in the large atomic explosions and radioactive fallout that occurs following a nuclear detonation.

The charge of an ion with 55 protons and 52 electrons is +3. the reason is because protons are positive, and there are three more than the amount of negative electrons.
