Question
Chemistry Question on Classification of elements & periodicity in properties
A nuclide of an alkaline earth metal undergoes radioactive decay by emission of three αparticles in succession.The group of the periodic table to which the resulting daughter element would belong is:
A
Group 14
B
Group 16
C
Group 4
D
Group 6
Answer
Group 14
Explanation
Solution
Atomic number drops by 6 after 3 alpha decays. and the daughter's atomic number drops by 6, and the parent atom is in the second group, she will be a member of the 14th group.
