Here’s what I get.
Explanation:
J. J. Thomson proposed that the electrons in an atom were embedded within a sphere of uniform positive charge, much like the raisins in a plum pudding (North Americans would call it a Christmas cake).
If that were the case, Rutherford reasoned, a stream of α particles should pass through the atom with little deflection.
Rutherford had his graduate students, Geiger and Marsden, shoot α particles through a thin gold foil.
Most of the particles passed through with little deflection, but a few rebounded back towards the emitter.
Rutherford concluded that most of the mass and all the positive charge in an atom was concentrated in a central nucleus with a cloud of electrons orbiting it like planets circling about the Sun.
His model is now called the nuclear model or the planetary model of the atom.
