Question 1.
What is an alpha particle?
Show hintHide hint
Think about its composition from helium.
Question 2.
What did Rutherford's gold foil experiment demonstrate?
Show hintHide hint
Recall the surprising results from the experiment.
3Question 3.
What did Rutherford's experiment discover about the atom?
- The atom is a solid ball

- Electrons are embedded
Show hintHide hint
Recall the main outcome of the gold foil experiment.
4Question 4.

- True
- False
Show hintHide hint
Think about the scattering data shown.
Question 5.
If Rutherford had directed an alpha particle beam at a solid piece of hydrogen instead of gold, what would you expect to happen, and why?
Show hintHide hint
Consider the atomic structure of hydrogen versus gold.
Question 6.
Calculate the effective size difference between the nucleus and the atom if the nucleus is ~10^-15 m and the atom is ~10^-10 m.
Show hintHide hint
Think about the ratio of their sizes.
