Chemists once believed that an atom was made of negative electrons dispersed inside a positive mass like raisins in pudding. An experiment with radiation and gold foil demonstrated that most of an atom was
made of empty space. After this experiment, they adopted a new model of the atom that showed the electrons orbiting the nucleus of the atom from a distance. Which of the following statements about the new
model is true?
The new model is perfect and will not change.
The new model is a wrong model and will not last.
The new model fits the data worse than the old model.
The new model fits the data better than the old model.
