(a) Due to emission of a β particle, the atomic number increases by 1 and the mass number is unchanged. Hence, the nuclear change is (b) Due to α emission, atomic number decreases by 2 and mass number decreases by 4. Also, an alpha particle is same as a Helium nucleus with 2 protons and 2 neutrons. Hence, we get the nuclear change as (c) When there is an α emission from , then the atomic number decreases by 2 and mass number decreases by 4. Hence, we get . Now, when undergoes β emission, the atomic number increases by 1 and the mass number is unchanged. Hence, we get . In the final step when undergoes β emission again the atomic number increases by 1 and the mass number is unchanged. Hence we get . So the complete nuclear change is as follows (d) When there is an α emission from , then the atomic number decreases by 2 and mass number decreases by 4. Hence, we get After the γ emission, there is no change in atomic number and mass number. Hence, we get In the final step when there are two β emissions, the atomic number increases by 2 and the mass number is unchanged and we get Hence, the nuclear change is as follows (e) The daughter nucleus is formed after α decay of , so atomic number of will be 2 units more and it's mass number will be 4 units more i.e., The nucleus is formed after α decay of so atomic number of will be 2 units more and it's mass number will be 4 units more i.e., The nucleus is formed after β decay of X, the atomic number will be one unit less and the mass number is unchanged i.e., Hence, the nuclear change is as follows
