`""_(88)""^(224)Ra` decays by a series emmision of three `beta-` particles and two `alpha-`particles. The end product of X isA. `""_(88)""^(220)X`B. `""_(87)""^(216)X`C. `""_(90)""^(234)X`D. `""_(88)""^(216)X`

Answer» Correct Answer - b
During the emission of `alpha` particle `Zdarr` by 2 units and `Adarr` by 4 units
During the emmision of `beta` particle `Zuarr` by 1 unit and A doesn t change
