Hm..I'd say everything here looks good so far :), but I think you you could include the basics of these or even add a hyperlink to the student doing quantum numbers: principle quantum numbers(n), angular momentum quantum numbers(l), magnetic quantum number, and the spin(+1/2, -1/2) edited 16:50, 8 Mar 2009

looks good. given the information you provide, looks like you understand the material enough and you know what information is most important. mayve you can give more examples? or not examples, but definitely practice problems. students may want as much help/practice as possible. good job!

You have summarized the main topics really well. Try to be more formal in some of your comments. Sentences such as “I'm writing this at one in the morning,” are entertaining, but not necessary to learning about electron configurations. Also, you mention that you must always put an upwards arrow before putting a downwards arrow in a box. This is not necessarily true. The arrows could be facing up or facing down, so long as the direction of the arrows is the same. It doesn't matter since the spin of the electron cannot be known without measuring it. Although you include some key concepts to electron configurations, you do not explicitly name the concepts. For example, you might want to mention the Pauli exclusion principle, Hund's rule, and the aufbau process. More examples may be needed to help explain how many boxes are required when writing the electron configuration; giving a step-by-step example with a picture would be useful to the reader. More problems would also be a good idea. Also, I noticed you wrote “varey” instead of “very” under the Outside Links heading. Otherwise, good job!

Synopsis: This module was about the various aspects of electron configuration. It discusses how to fill the orbitals and the rules that apply such as Hunds Rule, the Aufbrau process, and Pauli Exclusion Principle. It also discussed how to write electron configurations in depth and provided an example. The section on the s,p,d,f notation was very in depth.
Keywords: Electron configuration (google): some similarities but nothing word for word plagiarized
Noble gas notation (bing): none
Aufbau Process: none
Review Details: The module is rather long however there was a lot of information to cover so she did a good job of breaking up the information into sections as to not make it overwhelming. There are a few long paragraphs, maybe they could be broken up so they are not as intimidating to look at. Good job on providing lots of information and accurate information. There are a fair amount of spelling are grammar mistakes though that are distracting from the material so fix these and you are good to go!
I fixed a few errors: I corrected the spelling of a few words including necessary and periodic in the first paragraphs. Also I added a n "s" to make a noun and verb agree. No errors in the information were present, the information provided was all for informative and accurate. edited 18:02, 4 Dec 2009
Synopsis: The author begins by giving a few general ideas on electron configuration and introduces readers to the concept of orbitals and describes all 4 orbitals. Then, they show how the periodic table is split up into blocks depending on its position on the periodic table. Then we are introduced to the Pauli Exclusion Principle, Hunds Rule, and the Aufbau Process. After this we are introduced to a few different methods of writing electron configurations.

Review: This module is very good. It is a bit long but i see no way of shortening it and covering the topic thoroughly. I would suggest that you include hyperlinks to other chemwiki modules on such topics as Quantum Numbers, and orbitals. Adding a hyperlink to the module on orbitals in the first sentence will help readers understand what electron configurations exactly are before they read your module. There are also a lot of spelling mistakes that can be fixed quite easily using the spell check feature available in the editor.
Mistake: Changed "Thus familarizing oneself" to "Thus familiarizing oneself"
Synopsis:
Electron configurations are helpful in presenting an atom’s arrangement of electrons in their orbitals. Certain rules and exceptions apply when assigning electrons into their subshells. The Aufbau’s Process presents the shift of electrons between orbitals in order to reach a more stable electron configuration for certain atoms. The Hund’s Rule states that all orbitals must be filled with a positive electron spin before they are paired. The Pauli Exclusion Principle states that paired electrons within orbitals must have opposite spin directions; this is because no two electrons can have the same four quantum numbers. The electron notation and orbital diagrams are acceptable ways in representing electron configurations.
Review Details:
You seem to understand this topic very well and the concepts are nicely elaborated! This is a module that one can definitely learn from. There’s not much I have to critique about, but I do suggest that you may explain in more depth why the exceptions according to Aufbau’s process occurs. You may compare the accurate electron configuration to the unstable one that some may be mistaken for correct, therefore showing how electrons are moved from orbital to orbital in order to reach a more stable state. The table of exceptions is definitely helpful, but without explanation, viewers may depend on that table and try to memorize them all instead of understanding the concept.
It may also be helpful if you explain how to write electron configurations for ions.
Figures Questions:
1. The images are critical for understanding the results described in the text.
2. Images are nicely labeled and easy to interpret.
3. Figures are not referenced by numbers.
4. Additional images are not necessary, but may enhance the module even better than it already is.
Tables Questions:
1. Data presented in the table are accurately labeled with column headings.
2. The table has a meaningful title.
3. Table was not referenced by number.
4. The tabular way was an effective way of presenting the exceptions, but as said earlier above, enhance the explanation of Aufbau’s process by comparing one or two exceptions with their seemingly correct electron configuration.
5. No additional tables seem to be needed.
Text Questions:
1. The presentation of results are easy to follow.
2. Each paragraph has a topic sentence.
3. Spelling errors fixed.
4. There is a logical organization.
Fixed Mistake:
Corrected three “its” to “it is”
“This is why its sometimes useful to think about electron configuration in terms of the diagram. But because its the most time consuming method, its more common to write or see electron configurations in the spdf notation and noble gas notation.”
Plagiarism Checks:
Using the three plagiarism tools, no results and traces of plagiarism were found.
Figure Check:
Using the figure check tool, no results and traces of plagiarism were found regarding the images.
CHE 2A: Section C02
1. Synopsis: The electron configuration of an atom represents where the electrons are in the shells and subshells. The s, p, d and f blocks correspond to certain groups on the table. Orbitals fill starting with the lower energy orbitals and work its way up. Hunds rule states than a shell must fill up half way with all the same spins, before putting two electrons on one orbital. There are a few exceptions to the standard way to fill up orbitals, according to the Aufbau Process, so that the orbitals will have half-full shells. So an atom sometimes prefers two half full orbitals than one full and one partially full/not half full.
2. Everthing seems good! Well organized, its visually pleasing as well, which really helps us visual learners :) I would suggest more information on the Paulie Exclusion Principle, that part lacks clarity.
3. I think "Connecting Electron Configurations to the Periodic Table" and this Module need to sit down, have a talk and decide what each other will be covering. They are a little redundant and when you think about these two back to back in a book, it would be frustrating as a learner to read the exact same info again. The images are incredibly helpful and well done. Although I do not see each figure referenced by number in the text? I'm not sure what that means, but the FAQ page for Phase II asks for me to look for that.
4: Fix Module: Rephrased a few confusing sentences and did some formatting.
5. I used all three links, and no plagiarism.
6. Same with the figure check: no plagiarism.
