Ernest Rutherford was interested in knowing how the electrons are arranged within an atom. Rutherford designed an experiment for this. In this experiment, fast moving alpha (α)-particles were made to fall on a thin gold foil. He selected a gold foil because he wanted as thin a layer as possible. This gold foil was about …
Thomson proposed the model of an atom to be similar to that of a Christmas pudding.The electrons, in a sphere of positive charge, were like currants (dry fruits) in a sphericalChristmas pudding. We can also think of a watermelon, the positive charge in the atom is spread all over like the red edible part of …
