First, select the option of the right:

Do you remember the name of the scientist of the atomic model previous to Rutherford? And how he called that model?

Select the option traces to visualize the way of the alpha particles through the atom.

Observe and explain what happen when the particles are emitted to the atom.

Now, go to the option of the left:

Select the traces and press the source to start emitting alpha - particles to the atom.

Explain what happen and justify your answer.

How is the atom according to Rutherford after these experiments?
