11.1.1 Alpha-particle Scattering Experiment – Check yourself

Submit quiz
Once you submit, you will no longer be able to change your answers. Are you sure you want to submit the quiz?
1.
Most alpha particles passed straight through the gold foil. This shows that…
the nucleus is positive
the atom is mostly empty space
the nucleus is heavy
electrons are negative
2.
A few alpha particles were deflected through angles greater than 90°. This shows that…
the atom has a small, dense, positive centre
the atom contains neutrons
electrons orbit the nucleus
gold is a metal
3.
Why is the experiment carried out in a vacuum?
to stop the foil melting
to increase the charge of the nucleus
to prevent alpha particles being absorbed by air
to make the beam wider
4.
Why must the gold foil be very thin?
to give single scattering events
to let beta particles through
to make the nucleus smaller
to reduce the vacuum needed
5.
The diameter of an atom is about 10−10 m and that of its nucleus is about 10−15 m. The ratio is about…

1010
1015
6.
A graph shows number of alpha particles detected against scattering angle from 0° to 180°. The graph is best described as…
falling steeply from a large value at small angles
rising steadily
constant
rising then falling
