1.	How was it shown that an atom has a lot of empty space within it ?
Answer» Rutherford PERFORMED an experiment by allowing a STREAM of the ALPHA particles to pass through a very thin GOLD foil. He observed that alpha particles pass through the metal foil without deviating from their path. This shows that an atom contains a large empty SPACE called nuclear space.
