In the nuclear decay given below _ Z ^ A X _ Z +1 ^ A Y _ Z -1 ^ A -4 ~B ^* _ Z -1 ^ A -4 ~B , the particles emitted in the sequence are

Step-by-step solution

Key Idea In a nuclear reaction conservation of charge number and mass number must hold good. Alpha particles are positively charged particles with charge +2 e and mass 4 ~m . Emission of an -particle reduces the mass of the radionuclide by 4 and its atomic number by 2. -particles are negatively charged particles with rest mass as well as charge same as that of electrons. -particles carry no charge and mass. Radioactive transition will be as follows aligned & _ Z ^ A X _ Z +1 ^ A Y + _ -1 ^0 & _ Z +1 ^ A Y _ Z -1 ^
