Coz frm dis experiment...it was concluded that atom had concentrated +ve & -ve charge & relatively large mass. As most of the alpha particles passed straight through the foil,this shows that most of the atom is empty space. Thus he concluded that an atom was made of a very dense,positevely charged nucleus surrounded primarily by empty space in which electrons could be found.
