Th 90 232 emits 6 α and 4 β particles and gets converted into a lead. The mass number and atomic number of lead is _____

Options

  1. A208 , 82
  2. B82 , 208
  3. C210 , 82
  4. D210 , 84

Correct answer

A. 208 , 82

Step-by-step solution

In a nuclear reaction, conservation of mass and conservation of charge follows in other words we can say that mass number and atomic number are conserved. Th 90 232 = 6 α 2 4 + 4 β 1 0 + Pb 82 208 Hence, the mass number and atomic number of lead is, 208   and 82 .
