About This Quiz

Rutherford’s Gold Foil Experiment is what proved the existence of a small massive centre to atoms, which would later come to be known as the nucleus of the atom. What do you know about the experiment? Let’s have a look!

2. What first name or nickname would you like us to use?

You may optionally provide this to label your report, leaderboard, or certificate.

2. The white dots represent which of the following

Proton

Neutron

Electron

Photon

Positively charge "pudding"

3. Thomson predicted that alpha particle would be on be slightly deflected as it passed through the sheet of gold foil because he believed that the positive charge was spread out over the volume of the atom like a pudding

True

False

4. Referring to only the protons and neutrons what is the major difference between the two models

No major differences

5. The red dots represent which of the following

Proton

Neutron

Electron

Photon

Positively charged "pudding"

6. Step 1. Open the Plum Pudding atom. The blue dots represent which of the following?

Proton

Neutron

Electron

Photon

Positively charged "pudding"

7. As the alpha particle passes through the "pudding" which of the following best describes the path of the alpha particle.

The particle is deflected back to the gun

The particles are pulled towards the center

The particles are slightly (if at all) deflected

8. The "Ray gun" fires alpha particles. What are alpha particles made of

2 protons 2 neutrons

2 protons 2 electrons

4 protons

4 neutrons

4 little blobs of positively charges "pudding"

9. Step 2. Now open the tab titled "Rutherford's Atom". Referring to only the electron what is the major difference between the two models

No major difference

The electron are stationary in the Rutherford model but not in Thomson model

The electron is orbiting in the the nucleus in the Thomson model but not the Rutherford model

The electron is orbiting in the the nucleus in the Rutherford model but not the Thomson model

10. Of the two models which is correct?

Both

Neither, but the Rutherford model is closer to the excepted model

Neither, but the Thomson model is closer to the excepted model

Neither model is close to being correct
