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

View answer & explanation

Correct answer is C

$^{32} _{15}$ 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
