A nuclide of an alkaine earth metal undergoes radioactive deacy by emission of the `alpha-` particles in sucession. The group of the periodic tablle to which the resulting daughter element would belong to:

A

`Gr.14`

B

`Gr.16`

C

`Gr.4`

D

`Gr.6`

Text Solution

Verified by Experts

The correct Answer is:
A
`underset(Gr.2)(._(Z)A^(M)) overset(-alpha)rarr underset(Gr.18)(._(Z -2)B^(M-4)) overset(-alpha)rarr underset(Gr.16)(._(Z-4)C^(M -8))`
