scientists have changed the model of the atom as they have gathered new evidence. one of the atomic models is shown below.\nwhat experimental evidence led to the development of this atomic model from the one before it?\na few of the positive particles aimed at a gold foil seemed to bounce back.\nthe colors of light emitted from heated atoms had very specific energies.\nexperiments with water vapor showed that elements combine in specific proportions.\ncathode rays were bent in the same way whenever a magnet was brought near them.
Answer
Brief Explanations:
The atomic model shown has a nucleus with electrons in orbits, likely the Bohr - Rutherford model. The Bohr model was developed from the Rutherford model (nuclear model) based on the evidence of specific energy levels of electrons, shown by the specific energies of light emitted from heated atoms (atomic emission spectra). Option A is Rutherford's gold foil experiment (leading to nuclear model), Option C is about chemical proportions (not atomic model), Option D is about cathode rays (discovering electrons, leading to plum - pudding model). So the correct evidence is the specific energies of light from heated atoms.
Answer:
B. The colors of light emitted from heated atoms had very specific energies.
