1. In the figure above, nuclear radiation is escaping from a small hole in the lead box.

Which type of nuclear radiation is deflected

toward the positively charged electrode?

Why is this radiation deflected toward this

electrode?

2. Explain why the radiation that struck the

photographic plate was not deflected by

the electrodes.

what experimental evidence led scientists to change from the previous model to this one?

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.
