What experimental evidence led to the development of this atomic model from the one before it?
Scientists have changed the model of the atom as they
have gathered new evidence. One of the atomic models
is shown below.
O A few of the positive particles aimed at a gold foil
seemed to bounce back.
O The colors of light emitted from heated atoms had
very specific energies.
O Experiments with water vapor showed that elements
combine in specific proportions.
O Cathode rays were bent in the same way whenever a
magnet was brought near them.
