The Rutherford \[\alpha \]-particle scattering experiment shows that most of the \[\alpha \]-particles pass through almost unscattered while some of them are scattered through large angles. What information does it give about the structure of atom?      

Answer:

                (i) As most of a-particles pass straight, it indicates that most of the space in the atom is empty. (ii) The large angle scattering indicates that most of the mass and the entire positive charge of the atom is concentrated in a small central core, called nucleus.
