Answer:
solid particles are tightly held.
liquid particles have perfectly inelastic collisions
gas move in constant random motion
vapour
The atomic mass would be 13 amu.
You can calculate this by adding the number of protons and neutrons.
7 protons+6 neutrons
=13 amu.
Rutherford's result can not be explained on the basis of the plum pudding model because of the fact that, since some alpha particles were deflected, the atom must contain a small region with a strong electric charge.
The empirical study of the atom led to the emergence of several models of the atom. In the Plum - pudding model, the atom was regarded as a positively charged sphere with embedded negative charges.
This model can not interpret the Rutherford experiment since alpha particles were deflected. The deflection of alpha particles means that, the atom must contain a small region with a strong electric charge.
