Sometimes there is, depending on the type of decay. In the so-called "beta decy", the atom emits either an electron or an anti-electron.
Because the electric charge depends on the mass times the radius of a particle and whereas the mass of the proton is 1836 heavier than the mass of the electron, the radus of the proton is 1836 times smaller. Thus the product of mass times radius is in both paticles the same and therefore they have the same charge. Boy Boer
