For Rutherford's alpha scattering experiment where he fired alpha particles at a thin sheet of metal to determine the size of the nucleus, please can someone give me the direct link between his observations and his conclusions e.g. this observation lead to this conclusions.
This is a link with the conclusions from the experiment and which observations lead to which conclusions.
When Rutherford mathematically investigated the results he proposed a model that explained the results that Geiger and Marsden obtained.
The fact that the vast majority of the alpha particles got straight through led Rutherford to propose that the atom was composed primarily of empty space.
The fact that backscattering occurred in 1 in 8000 alpha particles indicated that the nucleus was:
