What occurs in Alpha Decay, and how penetrative is it?
gpt
In Alpha Decay, a helium 4 nucleus is emitted, making it the least penetrative type of radioactive decay, stopped by a sheet of paper.
Explanation: Alpha Decay is a type of radioactive decay where an atom emits an alpha particle, consisting of two protons and two neutrons, similar to a helium nucleus, resulting in minimal penetration power.
