(6) Most nuclei are stable. Consisting of protons and neutrons‚ they are unaffected by chemical reactions and have remained the same since they were formed. However‚ some nuclei are unstable and spontaneously release energy in the form of a Helium nucleus (α Alpha)‚an electron (β Beta) and γ Gamma rays. These nuclei are known as radioactive and it’s not possible to predict when a particular radioactive nucleus will emit this energy but a large number of materials are said to have a ‘half life’
