A radioactive decay can be represented as shown. 91Pa^233 ---> 92U^233 +...... The emitted particle is a/an?
Answer: β-emission
Explanation
The radioactive decay equation shows a parent nucleus (91Pa^233) decaying into a daughter nucleus (92U^233) with the emission of a particle.
The parent nucleus has an atomic number of 91 (Protactinium), and the daughter nucleus has an atomic number of 92 (Uranium).
This increase in atomic number indicates that a beta particle (β) has been emitted.
