For thorium , at the end of some radioactive disintegration we obtain an isotope of lead with and , then the number of emitted particles are
View answer and explanation
Correct option: C
Option C is correct because alpha decay reduces the mass number by 4 and the atomic number by 2, while beta decay leaves the mass number unchanged and increases the atomic number by 1. By setting up equations based on the changes in mass and atomic numbers, we can solve for the number of alpha and beta particles emitted.
