It is an alpha decay because when this phenomena occurs an atomic nucleus emits an alpha particle (helium nucleus) and consequentially decays into another atom with a mass number that is reduced by four an atomic number that is reduced by 2 two. The helium atom consists of two protons and two neutrons.
Therefore, the answer is <span>alpha decay because alpha particles have two protons and two neutrons</span>
