1
Due to Rutherford's experiment the atomic model was revised. This is an example of...
Why scientists do multiple trials of the same experiment.
How scientists just make things up.
How technology has helped scientists learn more about atoms.
how scientific theory changes based on new evidence.
2
What does the diagram below show happened during Rutherford's experiment?
Most of the alpha particles went right through the gold foil
Atoms are circular in shape.
Atoms have a negative charge overall.
The alpha particles looked like arrows.
3
Which model of the atom did scientists use prior to Rutherford's experiment?
Rutherford Model
Billiard Ball - Dalton
Plum Pudding - Thomson
Planetary - Bohr
4
Into what material did Rutherford fire alpha particles?
gold
copper
silver
aluminum
5
Which of the pictures below shows what Rutherford expected to happen in his experiment?
Neither - what are these pictures?
Bottom picture
Top picture
6
What part of the atom is Rutherford credited with discovering?
orbitals
x-rays
photons
nucleus
7
What caused the alpha particles to deflect upon hitting the gold foil?
nucleus
electron cloud
beta particles
neutron
8
Rutherford's experiment also proved this about the nucleus...
It is gold in color.
It is made of protons and neutrons.
It has great mass compared to the rest of the atom.
It can be seen with a microscope.
9
Why did most of the alpha particles go through the gold foil?
Alpha particles are very small.
He only fired particles at a 30 degree angle.
Atoms are mostly empty space.
Gold foil is very thin.
10
Rutherford also discovered this about the nucleus...
It is very small.
It matches the atomic mass on the periodic table!
It has the same number of protons as the atomic number!
It has a positive charge.
11
Scientists knew about this subatomic particle prior to Rutherford's experiment.
Electrons
Molecules
Protons
Nucleus
12
Rutherford used alpha particles in his experiment. An alpha particle is
a helium nucleus
protons
neutrons
negatively charged
