In ruther ford experiment he suggest that all the positive charge and mass are concentrated at the centre when he bombarded the alpha partical which is dipositive in nature and when it is more close to centre it get deflect to a large angle and with increase of closenes to centre its deflection angle increase and some alpha partical deflect to 180 degree so it prove that all the positive charge and mass are concentrated at the centre where as acccording to thomson atom is hard solid sphere in which its total +ve charge and mass uniformalyy distributed on the surface and electrone reside as seed in watermelon ( plum pudding model)

We know that the Rutherford model of the atom is superior to the Thomp...
Explanation:
The Rutherford model of the atom is superior to the Thompson model because when alpha particles are scattered from atoms, some alpha particles are deflected to large angles.
- The Rutherford model proposed that an atom consists of a positively charged nucleus at the center, surrounded by negatively charged electrons orbiting the nucleus.
- In contrast, the Thompson model proposed that an atom is a uniform sphere of positive charge with electrons embedded in it.
- To test these models, Rutherford and his colleagues performed an experiment in which alpha particles were fired at a thin sheet of gold foil.
When alpha particles are scattered from atoms:
- Alpha particles are positively charged particles consisting of two protons and two neutrons.
- When they are fired at a thin sheet of gold foil, most of them pass straight through the foil with little or no deflection.
- However, some alpha particles are deflected at large angles, and some even bounce back in the direction from which they came.
- This observation led Rutherford to conclude that most of the mass of an atom is concentrated in a small, positively charged nucleus at the center of the atom, while the electrons orbit around the nucleus.
Therefore, when alpha particles are scattered from atoms, the deflected angle is usually small, but some alpha particles are deflected to large angles, confirming the Rutherford model of the atom and disproving the Thompson model.
