Problem

Phosphorus-32 is a common tracer isotope in biochemistry. In a sealed sample it undergoes a decay that produces a daughter nuclide, an electron, and another light neutral particle. The incomplete symbolic description is

^{32}_{15}\text{P} \longrightarrow \; ? \; + \beta^{-} + ?

. (a) Determine the daughter nuclide and complete the nuclear equation using proper symbols. (b) Rewrite the completed equation from part (a) entirely in word form, naming every nucleus and particle. (c) Calculate the change in atomic number

Z

and in mass number

A

of the nucleus as a result of this decay.
