Scientists have changed the model of the atom as they have gathered new evidence. One of the atomic models is shown below. A pur
ple center outlined in black with two concentric black circles around the center, the inner circle having 2 small green balls on it and the outer circle having 8 small green balls on it. What experimental evidence led scientists to change from the previous model to this one?
A few of the positive particles aimed at a gold foil seemed to bounce back.
Explanation:
Some of the positive particles aimed at a gold foil seemed to bounce back which gives information to the scientists that some heavy particles present in the center of the atom which bounce back the positive particles. so from this evidence the scientists says that atom is divisible and having subatomic particles such as proton, electron and neutron. Proton and neutron is present in the center whereas electron is revolving around the nucleus of an atom.
