प्रश्न
Answer the following question.
Explain briefly how Rutherford scattering of α-particle by a target nucleus can provide information on the size of the nucleus.
उत्तर
- Most of the space inside the atom is empty became most of the α-particle passed through the gold foil without getting deflected.
- Very few particles were deflected from their path, indicating that the positive charge of the atom occupies very little space.
- A very small fraction of α-particle were deflected by very large angles, indicating that all the +ve charge and mass of the gold atom were concentrated in a very small volume within the atom.
