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 4

B

Gr 6

C

Gr 16

D

Gr 14

Text Solution

Verified by Experts

The correct Answer is:

D

Alkaline earth metals are Group 2 elements. Emission of `alpha`-particles will reduce its atomic number by units 2 . i.e., the daughter element may belong to group 18, 16, 14, 12, 10, 8, 6, 4, etc. As the end stable daughter nucleide formed should either be Pb (Gr 14) or Bi (Gr 15) , therefore , the correct answer is Group 14 (D).
