The number of beta particles emitter by radioactive sustance is twice

1.	The number of beta particles emitter by radioactive sustance is twice the number of alpha particles emitter by it. The resulting daughter is anA. Isobar of parentB. isomer of parentC. isoton of parentD. isotope of parent
Answer» Correct Answer - D Let the radioactive substance be `._(Z)^(A)X` Radioactive transition is given by `._(Z)^(A)Xoverset(-alpha)to`._(Z-2)^(A-4)X overset(-2beta)to._(Z)^(A-4)X` The atoms of element having the same atomic numbers but different mass numbers are called isotopes. So, `._(Z)^(A)X` and `._(Z)^(Z-4)X` are isotopes.
