Calculate the number of `alpha` and `beta` particles emitted in the conversion of `90^(Th^(232)` to `82^(pb^(208))`.

Text Solution

Verified by Experts

Let a and b be the number of `alpha beta` particles emitted during the change comparing the mass numbers
232 +208 +4a+b x0
4a=232-208
a=6
number of `alpha` paritcle emitted =6
number of `beta` particles emitted =4
