The model of the atom changed as new evidence was discovered. The plum pudding model suggested that the atom was a ball of positive charge with electrons embedded in it. Evidence from the alpha particle scattering experiment led to a change in the model of the atom from the plum pudding model. Explain how. PLS HELP RN :)
so since the model atom was changed as new evidence, and the plum pudding model was a ball of positive charge, the alpha particle scattering which broke up the atom
