An artificial radioactive isotope gave `._(7)^(14)N` after two success

1.	An artificial radioactive isotope gave `._(7)^(14)N` after two successive `beta-`particle emission. The number of neutrons in the parent nucleus must beA. 9B. 14C. 5D. 7
Answer» Correct Answer - A `._(x)X^(y) overset(2beta)rarr ._(7)N^(14)` `._(x =7-2)X^(y =14) = ._(5)X^(14)` Total no. of neutrons `= 14 - 5 = 9`
