Models For Hydrogen Atom
(244).jpg "Models For Hydrogen Atom - Quiz")
Objectives
· Connect the importance of inference from experimental data.
· Explain the concept of energy absorption and energy emission.
· Identify the significance of only specific wavelengths of light being absorbed or emitted.
Open the “Models of the Hydrogen Atom” simulation to the left
Turn the light on, if you leave the light controls to white it will produce photons at all wavelength, if turn it to monochromatic then it will only produce photons at one wavelength.
The spectrometer will measure photons deflected by the atom.
Start with "experiment" results then when asked turn to Read more"prediction"
Questions and Answers
- 1.
When determining how an atom works, scientists witnessed something similar to what you are witnessing now. They then deduced how the atom must be organized. What do you think is making the photons deflect? Is every color deflected?
- A.
Yes
- B.
No
- C.
Maybe
Correct Answer
A. YesExplanation
The given answer "yes" suggests that every color is deflected when photons are observed. This implies that when scientists observed the behavior of photons, they found that all colors of light were deflected, leading them to deduce that the atom must be organized in a way that causes deflection of all colors.Rate this question:

Make sure the spectrometer is on, let the spectrometer run for a couple minutes. How many band are formed
- A.
No bands
- B.
1
- C.
3
- D.
5
- E.
7
- F.
9
Correct Answer
F. 9Explanation
The correct answer is 9 because the question states that the spectrometer needs to be turned on and allowed to run for a couple of minutes. This suggests that the longer the spectrometer runs, the more bands will be formed. Therefore, after running for a couple of minutes, the spectrometer would have formed 9 bands.Rate this question:

From this data does it appear that atom only interact with specific wavelengths?
- A.
Yes
- B.
No
- C.
Maybe
Correct Answer
A. YesExplanation
The answer "Yes" suggests that from the given data, it appears that atoms only interact with specific wavelengths. This implies that atoms have a selective interaction with certain wavelengths of light or electromagnetic radiation, rather than interacting with all wavelengths indiscriminately. The data might indicate a pattern or evidence that supports this conclusion.Rate this question:

Take a snap shot of the spectrometer (the camera button) then switch to predictions. The billiard ball model is the Greek model. For some reason the spectrometer doesn't work for this prediction, but what kind of particles are been deflected by the atom?
- A.
Some
- B.
None
- C.
All
- D.
Just specfic photons
Correct Answer
C. AllExplanation
The question is asking about the particles that are being deflected by the atom. The correct answer is "all" because the question mentions that the spectrometer doesn't work for this prediction, implying that all types of particles are being deflected by the atom, not just specific ones.Rate this question:

Are the results from the billiard ball model the same for the "real" experiment?
- A.
Yes
- B.
No
- C.
Maybe
Correct Answer
B. NoExplanation
The answer is "no" because the billiard ball model is a simplified representation of the "real" experiment. In the billiard ball model, assumptions are made about the behavior of the balls, such as perfect elasticity and no external influences. However, in the "real" experiment, there may be factors like friction, air resistance, or imperfections in the balls themselves that can affect the results. Therefore, the results obtained from the billiard ball model are not expected to be exactly the same as those from the "real" experiment.Rate this question:

Change to the plum pudding model and reset the spectrometer, let the simulation run while collecting data on the spectrometer. Does the data from the plum pudding prediction match the data from the "real" experiment
- A.
Yes
- B.
No
- C.
Maybe
Correct Answer
B. NoExplanation
The given answer "no" suggests that the data from the plum pudding model does not match the data from the "real" experiment. This could be due to various reasons such as inaccuracies in the plum pudding model or errors in the simulation or data collection process. It indicates a lack of agreement between the predicted and observed results, highlighting a discrepancy between the two.Rate this question:

The solar system model just blows up so lets not go there. The next model is the Bohr model, reset the spectrometer and let the simulation run while collecting data. Does the data from the Bohr model prediction match the data from the "real" experiment
- A.
Yes
- B.
No
- C.
Maybe
Correct Answer
B. No -

The next model is the de Broglie model, reset the spectrometer and let the simulation run while collecting data. The de Broglie model is very close to the "real" experiment. If you were unable to "see" into the infrared. Would the data from the de Broglie prediction match the data from the "real" experiment
- A.
Yes
- B.
No
- C.
Maybe
Correct Answer
A. YesExplanation
The explanation for the correct answer "yes" is that the de Broglie model is very close to the "real" experiment. If the de Broglie model accurately represents the behavior of particles in the experiment, then the data from the de Broglie prediction should match the data from the "real" experiment. Therefore, the data from the de Broglie prediction would indeed match the data from the "real" experiment.Rate this question:

The last model predicts the band collected from the "real" experiment
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is suggesting that the last model accurately predicts the band collected from the "real" experiment. This means that the model has been successfully trained and validated to accurately replicate the results of the actual experiment. Therefore, the answer is true.Rate this question:
