Question

whats its answer of this question

Answer 1

Answer:

6 alpha particles and 4 beta particles

Explanation:

The mass number of Thorium is 232 and the mass number of Lead is 208. There is a difference of 24 mass numbers. 1 alpha particle reduces 4 mass numbers. So, 24/4=6 alpha particles.

The proton number of Thorium is 90 and the proton number of Lead is 82. There is a difference of 8 proton numbers while according to the above statement the difference should be of 12 proton numbers. The difference is less because of the emission of beta particles. 12-8=4 beta particles were emitted leaving a difference of only 8 proton numbers.
