The type of decay which has the greatest mass is the alpha decay. An unstable
nucleus loses the most mass if the nucleus emits an alpha particle. This type
of decay has the largest mass among the radioactive
decay. When this particle is emitted from a nucleus, it loses two protons
and two neutrons therefore large amount of mass is lost.
The law conservation of mass, because part of the mass can be converted into energy
also, the elements are changing during nuclear reactions, new elements are formed
365 days.
Solar years is what we go by.
