[Jawaban] Phosphorus -32 (P-32) can decay by emitting beta particles. (a) What is a beta particle? A high-energy, high-speed electron or positron emitted from an atom's nucleus during beta decay. (b) If the proton number of phosphorus -32 is 15: i) State the new values of proton and mass number of the nuclide just after it emits a beta particle. ii) Write the decay equation for P-32 after emitting two beta particles. (c) Phosphorus -32 can be used to prove that plants absorb phosphorus nutrients from the soil around them. State one safety precaution which should be taken into consideration when doing experiments with phosphorus -32.
