A radioactive decay can form an isotope of the original nucleus with the emission of particles

A

one `alpha` and four `beta`

B

one `alpha` and two `beta`

C

one `alpha` and one `beta`

D

four `alpha` and one `beta

Text Solution

Verified by Experts

The correct Answer is:
B
`""^(A)X_(z)overset(alpha)rarr""^(A-4)X_(z-2)overset(2beta)rarr""^(A-4)X_(z)`
So, radioactive decays can form an isotope of the original nucleus with the emission of one `alpha` and `2beta` particle.
