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. experiments with water vapor showed that elements combine in specific proportions. cathode rays were bent in the same way whenever a magnet was brought near them.
Answer
Brief Explanations:
The image shows a nuclear - model of the atom. The Rutherford gold - foil experiment, where a few positive particles (alpha particles) aimed at a gold foil bounced back, led to the development of the nuclear model of the atom. This experiment showed that the atom has a small, dense, positively - charged nucleus. The other options are related to different atomic concepts: the colors of light from heated atoms are related to the Bohr model and energy levels, elements combining in specific proportions is related to Dalton's atomic theory, and cathode rays being bent by a magnet is related to the discovery of electrons.
Answer:
A. A few of the positive particles aimed at a gold foil seemed to bounce back.
