alpha particles are doubly charged helium ions. Since they are much more heavier than electrons, they would not get deflected upon collision with electrons. We get to know that most of the space inside the electrons is either empty or comprises of electrons.....but how can we directly conclude that the space inside an atom is empty through the alpha particle experiment? It can also be that its is not empty and comprises of electrons.......
1. Alpha particles are the positively doubly charged particles.
2. An electrons are negatively charged species.
3. When a thin layer of electrons is stricken by a beam of protons,they bounce back and hit the screen.
4. However,as we know,beam contains a lot of positively charged particles and electrons are very few in that thin layer so very few revert back,many go undeviated and we conclude that there is a lo of empty space in an atom.
