प्रश्न
How was it shown that an atom has a lot of empty space within it?

उत्तर
Rutherford's alpha- particle scattering experiment demonstrated that there is a lot of empty space in an atom. Almost all the alpha particles passed through the gold foil without any deflection. This is possible only when a higher fraction of space in an atom is empty.
