Answer:

A radium nucleus is a massive nucleus of 226 nucleons, including 88 protons and 138 neutrons. It decays by emitting an alpha particle composed of two protons and two neutrons. The radium nucleus turns into radon-222 nucleus, itself radioactive, containing two protons and two neutrons less.
