Alpha particles are the least penetrating form of radiation.
However, that does not mean they are the least dangerous. Even though they can be stopped with only an inch or so of air, or even by our skin, if they are ingested and come into contact with sensitive body tissues, they can be dangerous, because they have the highest charge and the highest mass.
Alpha radiation is the least penetrating form of a reaction.
A chemical equation is the graphic form of the reaction.
Endothermic.
Endothermic reaction
A precipitation reaction is usually a double displacement reaction. The ions that do not form the precipitate usually form the solution.

alpha
Is this the reaction to form water, or some combustion reaction? Resubmit with that detail at least.
alpha, beta, gamma
Alpha radiation.
gamma rays
Yes and they are a penetrating form of radiation.
Gamma Beta Alpha
The gamma ray because a photon does not have electric charge and is thus does not experience force in a EM field. All the others are charged particles
The Least penetrating form of radiation is Alpha as it only travels 10cm in air and is stopped by paper. Alpha is also the most ionising, Beta is less ionising still and Gamma is the least ionising as photons carry no charge so they have less effect.
Gamma
That would be a type of chemical reaction, although it is not the only type.
