Question

in Rutherfords expirement when the alpha particles hit the foil , Rutherford expected that all the alpha particles would be deflected by small angles why did Rutherford expect the above observation
​

Answer 1

Answer:

Rutherford expected the above observation because in his observation he thought that the cells have the empty spaces through which the Alpha particles move down and which hits the nucleus go to the the other direction with small angles and the large angles but only one Alpha particles from 1000 came back to his original path so he observe it

Answer 2

Answer:

Rutherford's Gold Foil Experiment. Rutherford expected the alpha particles to pass through the Plum Pudding Model of the atom undisturbed, but he observed that a small portion of the particles were deflected, indicating a small, concentrated positive charge
