उत्तर
(i) α particle is represented by 2He4 this means it contains 2 protons so after emitting a α particle atomic number of element would decrease bv 2 unit.
(ii) β particle is represented by -1θ° after emitting a β particle atomic number of element would increase bv 1 unit.
(iii) Y radiations have no charge and no mass so after emitting a Y radiation atomic number of element remain unchanged.
