Alpha,beta and gamma decay
equations
Alpha decay is the emission of 2
protons and 2 neutrons from the
nucleus
Can be
represented by
Helium
Mass number falls by 4 and atomic
number falls by 2
The LHS and RHS of the equations
must balance
Beta is an electrons being ejected
from the nucleus
For this to happen a neutron changes
into a proton
Mass number stays the same but
atomic number increases by 1
Gamma is just surplus energy
Gamma emission makes no change to
the atomic number or mass number
