Since an alpha particles is a helium nucleus, it involves the loss of 2 protons and 2 neutrons. As a result, the atom the loses an alpha particle decreases its mass number by four ( 2 protons and 2 neutrons) and decreases it's atomic number by 2 ( it loses two protons).
The density of the material is 32/3 or 10 2/3 g/cm^3
When a stable atom gains or loses its electrons then that’s when it becomes the ion.
