Rutherford scattering experiment diagram
Answers
»Rutherford bombarded a thin gold foil with high speed alpha particles which are obtained from radioactive material
»Alpha rays are made to travel in straight lines by passing them through Lead sheets having holes at their centres .zinc sulphide screen was placed behind the gold foil to know the position of the alpha rays .
Rutherford observed that :
most of the Alpha particles passed without any deflection
some of them were deflected away from their path
only a few were returned back to their original direction of propagation
Rutherfords atomic model:
the main features of this model are
atom is Spherical and hollow
the total mass and total positive charge is concentrated in a small region at the centre part of the atom which is called in nucleus
this model is called solar Model or planetary model
electrons and nucleus are held Together by electrostatic force of attraction
