Answer: For the reaction of radon getting converted to polonium, we get one alpha particle.
Explanation: The given reaction is a type of radioactive decay reaction.
Radioactive decay process is a type of process in which a less stable nuclei decomposes to a stable nuclei by releasing some radiations or particles like alpha, beta particles or gamma-radiations.
The given reaction follows:
[tex]_{86}^{222}\textrm{Rn}\rightarrow _{84}^{218}\textrm{Po}+_2^4\alpha[/tex]
In a given reaction, one alpha particle is released which has 2 neutrons and 2 protons.
This reaction is a type of alpha-decay reaction because a alpha-particle is released during the decay process.
Hence, in the reaction, one alpha-particle is released.
