The emission of two successive beta particles from the nucleus (^{32} _{15} P) will produce
-
A.
(^{30} _{14})Si -
B.
(^{32} _{13})Al -
C.
(^{32} _{17})Cl -
D.
(^{32} _{16})S
Correct Answer: Option C
Explanation
(^{32} _{15})P (to) 2(^{0} _{-1})e + (^{a} _{b})X
32 = 2(0) + a
a = 32
15 = 2(-1) + b
b = 15 + 2
b = 17
(therefore) (^{a} _{b})X = (^{32} _{17})Cl
