Question 28

Which equation represents the β\betaβ-decay of phosphorus-32?

A

1532P+ −10e→ 1632S^{32}_{15}\text{P} + \text{ }^{0}_{-1}\text{e} \rightarrow \text{ }^{32}_{16}\text{S}1532​P+ −10​e→ 1632​S

B

1532P+ −10e→ 1432Si^{32}_{15}\text{P} + \text{ }^{0}_{-1}\text{e} \rightarrow \text{ }^{32}_{14}\text{Si}1532​P+ −10​e→ 1432​Si

C

1532P→ 1632S+ −10e^{32}_{15}\text{P} \rightarrow \text{ }^{32}_{16}\text{S} + \text{ }^{0}_{-1}\text{e}1532​P→ 1632​S+ −10​e

D

1532P→ 1432Si+ −10e^{32}_{15}\text{P} \rightarrow \text{ }^{32}_{14}\text{Si} + \text{ }^{0}_{-1}\text{e}1532​P→ 1432​Si+ −10​e
