According to the research, alpha particles are a type of radioactive emission that has a positive charge and weak penetrating power.
What is a alpha particle?
They are very heavy particles that have a positive charge and are composed of two protons and two neutrons from the nucleus of the atom.
That is to say, it is a completely ionized nucleus, without its ideal electron coating, identical to the Helium nucleus and they are of low penetrability.
Therefore, we can conclude that according to the research, alpha particles are a type of radioactive emission that has a positive charge and weak penetrating power.
