scientists have changed the model of the atom as they have gathered new evidence. one of the atomic models is shown below. what experimental evidence led to the development of this atomic model from the one before it? a few of the positive particles aimed at a gold foil seemed to bounce back. the colors of light emitted from heated atoms had very specific energies. equations were used to identify regions around the nucleus where electrons would likely be. cathode rays were bent in the same way whenever a magnet was brought near them.
Answer
Answer:
A. A few of the positive particles aimed at a gold foil seemed to bounce back.
Explanation:
Step1: Identify the atomic model
The given model is similar to the Rutherford - model precursor.
Step2: Recall the key experiment
Rutherford's gold - foil experiment, where positive particles (alpha particles) were shot at gold foil and some bounced back, led to the discovery of a small, dense, positively - charged nucleus, changing the previous model. This evidence is consistent with option A.
