    I like your figures, and the module is well organized. For the fission section, you should spell check and make sure the capitalization is uniform. (That's being nit-picky though). Good job overall.

    i would add where and why the fusion and fission starts and stops.

    Your module is good overall..you should hyperlink more for important words though. good job

    you should add more examples to explain the process a bit more. but great job so far.

    i would give some examples of where fission and fusion occur in nature, some possible and more current application of the two, the energy difference in the product of both. Provide more background about the two processes.

    Synopsis: Fission is breaking apart the nucleus to produce smaller nuclei. On the other hand, fusion joins the nuclei together to produce a larger nucleus. These two processes releases energy. The natural state of an element includes the mass of protons and neutrons are considered. By taking these factors into consideration, the energy that is released is called the nuclear binding energy. To calculate the energy, you use Einstein's equation E=mc^2.

    Keywords: Nuclear binding energy, Fusion, Fission
    Search Engine Used: Google
    The author acknowledged the sources used to determine the definitions of each key word. Thus, there is no plagarism .

    Review Details:
    The author could have included problems that dealt with fission and fusion so readers can apply the concept. The length is kind of short. The format is easy to comprehend and transitions well. At times, the sentences are wordy.

    I fixed some of the grammar in the module. I changed the phrase "the energy that is released.." to "the energy released.." edited 02:15, 4 Dec 2009

    Module Title: Fission and Fusion
    Module Author(s): Veena Kumar

    Specific Questions: (1) Does the module fall within the scope of the Journal? There is no journal cited.
    (2) Are any statements made which you consider unjustifiable? No.
    (3) Are there any apparent errors of fact or logic? No.
    (4) Is the length of the module appropriate? Yes, short and concise.
    (5) Is the summary informative? Yes
    (6) Are the figures appropriate? Yes
    (7) Is the module format useful (e.g. not excessive colors or awkward formulations)? Yes the format is easy to read.

    Recommendation:
    Select one: 2) Publish with minor revisions

    Synopsis: This module introduces the process of fission and fusion. It explains these two reactions produces nuclear energy. To account for nuclear binding energy, we can use Einstein’s equation that incorporates energy and mass.

    Details: The module is concise and straightforward. It follows most of the proposed outline for the module, but does not include any possible problems. The details seemed justifiable and logical. The figure were useful, but can possibly be made more neatly; the external link is helpful. Maybe more figures can be added, such as, showing the process of fission and fusion. The format of the module is easy to read and organized.

    Specific Points to fix:
    1. Create five possible problems to enhance the learning of fission and fusion.
    2. Create more figures to help picture the process of fission and fusion.
    3. Reword some of the introduction to make it easier to understand
    4. Link related modules to help understanding nuclear energy
    5. Maybe include background facts about how fission and fusion were discovered, just to make the module more interesting.

    1. Synopsis: This module is about fission, which is the splitting of the nuclei and fusion, which is the joining of two nuclei. This module also shows the relationship between mass and energy by using Einstein’s famous equation, E=mc2.

    2. Keywords: A) “Nuclear binding energy” Google search engine. B) “Nuclear fission” Google search engine. C) “Nuclear fusion” Google Search engine. No plagiarism was detected.

    3. Review Details: The author of this module can add pictures of what nuclear fission and fusion, add hyperlinks to other Chem Wiki modules, tidy up the graph, and establish a relationship between chemistry to the “real world”, for example, what are the applications of nuclear fission to the “real world”? The length of this module is a bit short. The overall format of this module is correct, except it is missing a “Problem” section.

    4. Fix one mistake in the Module: In the section of “Fusion”, I changed “a lot of” to “the” and “driven a” to “applied in”.

    1. Synopsis: The module provides the explanation about two kinds of nuclear reactions: fusion & fission. While a nuclear fusion process is to combine nucleus of at least two smaller elements and become a larger element; on the other hand, a nuclear fission process is to separate a nuclei of a larger element and become smaller elements. These processes can both release energy, but the nuclear fusion process can release more energy and is harder to be control than the nuclear fission process.

    2. Yes, this module can go to Vet2.

    3. Review Details:
    3.1. In overall, the module provides a clear explanation of two separate nuclear processes. However, the paragraph about the critical mass seems unclear to the reader when the author mentions “the probability per second” as “the spontaneous nuclear fission rate,” but does not provide a clear connection with a critical mass’s concept.
    3.2 It is great that the author provides the graph that helps explain about the nuclear binding energy; however, to further develop, the author should incorporate the graph into the text (put it into words). If possible, the pictures of nuclear fission in reality (such as the real event’s picture of using nuclear fission during WWII) should be added (I am not sure that whether those pictures are on commercial websites or not).
    3.3 For further development, I think it will be easier for the reader to have a table, which summarizes the similarity and the differences between nuclear fission and fusion processes.

    4. I have deleted and added some articles (the & a) and changed some minor errors, such as adding hyphen(-) and capitalizing "Uranium".
    5. No plagiarism has been found.
    6. The picture is not on a commercial website.
