5.2.3a Radioactive decay

The chemical symbol for phosphorus is $P\text{P}$ . The equation represents the radioactive decay of phosphorus-32 to sulfur-32 ( $S\text{S}$ ).

\mathrm{^{32}_{15}P \rightarrow ^{32}_{x}S + ^{y}_{-1}e}

What are the numbers $x\,$ and $y$ ?

$x = 14$ , $y = 0$

$x = 14$ , $y = 1$

$x = 16$ , $y = 0$

$x = 16$ , $y = 1$
