Explain how experimental evidence led scientists to suggest the
nuclear model of the atom,

In 1909 Ernest Rutherford designed an experiment to test the plum pudding model. In the experiment, positively charged alpha particles were fired at thin gold foil. Most alpha particles went straight through the foil. This evidence led Rutherford to suggest a new model for the atom, called the nuclear model
