Hey friend he concluded the following things:-
1) He concluded that most of the particles of atom are empty because most of the α-particles passed without getting deflected from the gold foil.
2) Some of the α- particles were deflected for a long distance 90° or more. From this he concluded that alpha particles are positively charged.
3) Since the alpha which bounced back were very small therefore volume occupied by the nucleus is very small as compared to the total volume of the atom.
Hope this helps.....

RUTHERFORD'S MODEL OF ATOM
Rutherford's model of atom was similar to the solar system.The planets revolve around the Sun. Similarly, the electrons revolve around the nucleus. He called these electrons planetary electrons.
Postulates( Conclusions) :
1) There is a positively charged,highly densed center in an atom, called nucleus.Almost, the whole mass of atom resides in the nucleus.
2) The electrons revolve around the nucleus in an arbitary manner.
3) The size of a nucleus is very small as compared to atom.A nucleus can be compared with a cricket ball in a cricket stadium which is the atom.
Limitations :
1) Any charged particle is expected to radiate energy when accelerated.To remain in the orbit the electron has to undergo acceleration,so it would radiate energy.
The electron after radiating energy will finally collapse into the nucleus.If this happens then matter would not exist;but matter exists so atoms are stable.
