Question

In the following radioactive decay `x^(232)rarry^(220)` how many `alpha` and `beta` particles are ejected from x to y?
A. `3 alpha and 2 beta`
B. `5alpha and 3 beta`
C. `3alpha and beta`
D. `5alpha and 5 beta`

Answer 1

Correct Answer - C
By mean of emission of an `alpha` particle the atomic number is decreased by 2 units while mass number is decreased by 4 units but in case of emission of one `beta` particel the atiomic number is increased by 1 units while mass number is not affected.
`_(92)X^(232)overset(-3alpha and)(rarr_(89))Y^(220)`
