    Rutherford, in his trial, coordinated high energy floods of α-particles from a radioactive source at a slight sheet (100 nm thickness) of gold. To concentrate on the avoidance caused to the α-particles, he set a fluorescent zinc sulfide screen around the slight gold foil. Rutherford mentioned specific objective facts that went against Thomson’s nuclear model.

    Observations of Rutherford’s Alpha Scattering Experiment:

    The perceptions made by Rutherford drove him to presume that: A significant part of the α-particles assaulted towards the gold sheet went through it with next to no diversion, and subsequently, a large portion of the space in an atom is empty.

    A portion of the α-particles was deflected by the gold sheet by very small angles, and henceforth the positive charge in a molecule isn’t consistently disseminated. The positive charge in a molecule is packed in a tiny volume.

    Not many of the α-particles were diverted back, that is a couple of α-particles had almost 180-degree points of redirection. So the volume involved by the decidedly charged particles in a molecule is atom when contrasted with the all-out volume of an atom.
