Q83 / 200 · NEET 2005 · Chemistry

A nuclide of an alkaline earth metal under goes radioactive decay by emission of the $\alpha$-particles in succession. The group of the periodic table to which the resulting daughter element would belong is:

  • A
    Gr. 4
  • B
    Gr. 6
  • Correct answer
    C
    Gr. 14
  • D
    Gr. 16

Solution
