प्रश्न
Enlist the conclusions drawn by Rutherford from his α-ray scattering experiment.
Advertisements
उत्तर
Rutherford concluded from a-particle scattering experiment that
- Most of the space in the atom is empty because most of the α-particles passed through the gold foil without getting deflected.
- A small fraction of a-particles were deflected indicating that the positive charge of the atom occupies very little space. A very small fraction of α- particles were deflected by 180°, indicating that all the positive charge and mass of the atom were concentrated in a very small volume within the atom.
From the data, Rutherford also concluded that the radius of the nucleus is about 105 times less than Mg2+ the radius of the atom
