If the electron escapes the Hydrogen atom is positively ionized. Similarly, the Hyrogen atom can sometimes bind another electron to it. Such a Hydrogen atom is negatively ionized

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.
