5. The chart below lists 4 different "atoms" (A, B, C, D). Tell me what you know about each of them, comparing A to B, then A to C and then A to D. Remember to use Atom "A" as the reference and consider how "B" is different from "A". (Hint: using the material in your book, when an atom gains or loses electrons, what does it become?) Then look at how "A" and "C" are similar and different and then "A" and "D".

Your friend tells you about an article that he read in a tabloid that reported the discovery of a new form of carbon containing eight protons in the nucleus of its atoms. He claims that scientists are eager to explore the properties of this new form of carbon. What is wrong with the tabloid's claim? a. Nothing. The claim is believable. b. The claim must be false because an atom with eight protons would be oxygen, which is already known. c. The claim must be false because all forms of carbon are already known.
One of the best indications of a useful theory is that it raises more questions for further experimentation than it originally answered. How does this apply to Dalton’s atomic theory? Give examples.
A chemistry instructor makes the following claim: Consider that if the nucleus were the size of a grape, the electrons would be about I mile away on average. Is this claim reasonably accurate? Provide mathematical support.
Predict and test the behavior of a particles fired at a Rutherford atom model. Predict the paths taken by a particles that are fired at atoms with a Rutherford atom model structure. Explain why you expect the particles to take these paths. If a particles of higher energy than those in (a) are fired at Rutherford atoms, predict how their paths will differ from the lower-energy a particle paths. Explain your reasoning. Predict how the paths taken by the particles will differ if they are fired at Rutherford atoms of elements other than gold. What factor do you expect to cause this difference in paths, and why? Now test your predictions from (a), (b), and (c). Open the Rutherford Scattering simulation (http://openstaxcollege.org/I/16PhetScatter) and select the Rutherford Atom tab. Due to the scale of the simulation, it is best to start with a small nucleus, so select 20 for both protons and neutrons, mm for energy, show traces, and then start firing a particles. Does this match your prediction from (a)? If not, explain why the actual path would be that shown in the simulation. Pause or reset, set energy to max, and start firing a particles. Does this match your prediction from (b)? If not, explain the effect of increased energy on the actual path as shown in the simulation. Pause or reset, select 40 for both protons and neutrons, mm for energy, show traces, and fire away. Does this match your prediction from (c)? If not, explain why the actual path would be that shown in the simulation. Repeat this with larger numbers of protons and neutrons. What generalization can you make regarding the type of atom and effect on the path of a particles? Be clear and specific.
It is good practice to actively read the textbook and to try to verify claims that are made when you can. The following claim is made in your textbook: “. . . if the nucleus were the size of a grape, the electrons would be about 1 mile away on average.” Provide mathematical support for this statement.
Without consulting your textbook or notes, state as many points as you can of Dalton’s atomic theory. Explain in your own words each point of the theory.
Explain the operation of a cathode-ray tube. Describe the deflection of cathode rays by electrically charged plates placed within the cathode-ray tube. What does this imply about cathode rays?
What are the different kinds of particles in the atoms nucleus? Compare their properties with each other and with those of an electron.
Here are three fictitious elements and a molecular view of the atoms that compose them. The molar mass of the middle element, (b), is 25 grams per dozen (g/doz). (The atoms of these fictitious elements are much larger than ordinary atoms.) Based on the size of the atoms, do you expect the atomic masses of elements (a) and (c) to be greater than or less than (b)? How many atoms are present in 175 g of element (b)?
What evidence led to the conclusion that cathode rays had a negative charge?
A fundamental idea of Daltons atomic theory is that atoms of an element can be neither created nor destroyed. We now know that this is not always true. Specifically, it is not true for uranium and lead atoms as they appear in nature. Are the numbers of these atoms increasing or decreasing? Explain.
How would you expect the chemical properties of isotopes of the same element to compare to each other? Explain your answer.
