What is the conclusion of alpha-ray scattering experiment? |
|
Answer» Solution :The conclusion of `alpha` -ray scattering experiment is atoms inside gold are closely packed, `alpha` particles must have PASSED through the atoms. (a) Since most of the `alpha` - particles SIMPLY passed through, most part of the atom should be empty space. (b) Since a few of the`alpha` particles got DEFLECTED by small angles, they must have COME across a positive part which would repel them. (c) Since only one out of 20000 `alpha` particles retracted then path, the size of the positive part in the atom should be extremely small, only those particles which MADE a head on collision with the nucleus would retrace their path. |
