Answer 1

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:

`_(86)^(222)\textrm{Rn}\rightarrow _(84)^(218)\textrm{Po}+_2^4\alpha`

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.

Answer 2

The reaction being demonstrated is that of alpha decay. An alpha particle is equivalent to a helium nucleus, which means it contains two neutrons and two protons. Thus, one alpha particle is released and the reaction equation is:
Rn → Po + α
