Question 12

Phosphorus-32 (1532P{}^{32}_{15}\text{P}1532​P) is a radioactive isotope used in clinical medicine to locate and treat certain tumors. It undergoes beta-minus (β−\beta^-β−) decay.

Which equation correctly represents the beta-minus decay of a phosphorus-32 nucleus?

A
1532P→1632S+−10e+νe {}^{32}_{15}\text{P} \rightarrow {}^{32}_{16}\text{S} + {}^{0}_{-1}e + \nu_e 1532​P→1632​S+−10​e+νe​
B
1532P→1632S+−10e+νˉe {}^{32}_{15}\text{P} \rightarrow {}^{32}_{16}\text{S} + {}^{0}_{-1}e + \bar{\nu}_e 1532​P→1632​S+−10​e+νˉe​
C
1532P→1432Si++10e+νˉe {}^{32}_{15}\text{P} \rightarrow {}^{32}_{14}\text{Si} + {}^{0}_{+1}e + \bar{\nu}_e 1532​P→1432​Si++10​e+νˉe​
D
1532P→1632S+−10e {}^{32}_{15}\text{P} \rightarrow {}^{32}_{16}\text{S} + {}^{0}_{-1}e 1532​P→1632​S+−10​e
