Question

What happens to the atomic number of element when (i) An α -particle, (ii) A β -particle 1 and (iii)  γ-radiation is emitted?

Answer 1

(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 -1^θ° 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.
