Group 15: The Nitrogen Family

    Table of contents
    No headers
    1. Synopsis
    The nitrogen family includes Nitrogen, Phosphorous, Arsenic, Antomony, and Bismuth. The module gives a clear description of each of these elements with respect to both physical and chemical properties. For example, nitrogen is the most electronegative element and most of its commercial use comes in the form of N2(g). Phosphorous comes from apatite ores and is not commonly found in nature, and can exist as white phosphorous (toxic) and red phosphorous (a more stable form and therefore nontixic). Phosphorous also has many commercial uses. Arsenic has many oxidation states and is a very poisonous metalloid. Antimony shares many of the same properties, including high density and moderate thermal conductivity. Bismuth exhibits the most metallic properties of Group 15 and has the lowest electronegativity. 
     
    2. Yes this module is ready for Vet2 level. There are no mispellings and the information is organized in a clear manner. There is a helpful chart that displays properties of each element and gives an accurate summary of important information.
     
    3.
    Figure Questions
    a) The image of the periodic table with the highlighted Nitrogen group is helful for understanding where the the Nitrgoen Family is in relation to other groups. The image of the Lewis structure of N2 is also helpful in understanding how nitrogen bonds to itself in its most common form. 
    b) There is no legend provided for the figure, but it is not necessary.
    c) The figures are not referenced by a number in the text.
    d) The images provided are sufficient as they are now.
    e) It may be helpful to add images of each element in the family so students have an understanding of their physical properties and how they differ. These images could also be helpful for students to have a deep understanding in how the chemistry of each element affects their uses in everyday life.
     
    Table Questions
    a) The table displaying information on each element is appropriately labeled with the following titles; atomic mass, electron configuration, radius, electronegativities, and ionization energy. These properties are important for understanding how each element relates to one another in a clear pattern.
    b) Yes, the table has a meaningul table so students understand what they are viewing.
    c) There is no reference to a number in the text.
    d) The tabular format for this information is the best way to present the data for clear understanding of the trends, because it depicts clear trends.
    e) There are no other tables necessary for this module.
     
    Text Questions
    a) The presentation of each element is easy to follow because each element is listed going down the row.
    b) Yes, there is a topic sentance for each paragraph that introduces the element and a key properries including common oxidation states and commercial uses of each element.
    c) There are no distracting grammatical or syntactical errors, a few minor spelling errors that I have fixed but nothing that distracts from the information presented.
    d) There is a logical flow of information, and it is presented in the most clear manner, which is a description of each element going down the row. There are also very helpful questions that test the students understanding of the material and will give the student feedback on what they need to work on.

    I would suggest starting the module with information you state saying "The Nitrogen Family is group 15...." and then have the image of the periodic table

    You have very nice and neat images. I agree with Parisa. Start with an introduction instead of pictures. Even though we know we are reading about the nitrogen family, it is natural to read the text and refer to the picture. It disturbs the flow to scroll down, read the text, and must scroll back up to refer to the images.

    Group 15 in the periodic table refers to the Nitrogen family. Each element in the family has a ns^2np^3 electron configuration.  Nitrogen makes up 78% of the Earth’s atmosphere.  It can also be found on Mars and Venus. Bismuth is a poor metal which is comparable to Antimony and Arsenic, both of which are metalloids.

    2.       No, I think more information regarding each element and their applications is needed. Also,  there should be more information about the overall trends and properties of the groups.

    3.       Figure  Questions:

    1.       Yes,

    2.       Only for the N2 triple bond figure.

    3.       No

    4.       The figure of Phosphorus could be better explained, and be more clearly connected to the given information.

    5.       I figure illustrating the Haber-Bosch would be helpful. Also, pictures of red and white Phosphorus would be nice.  

      Table Questions:

    1.       Yes

    2.       No

    3.       No

    4.       I think the table was the best way to display the given information

    5.       I don’t think additional tables are needed, but it would be beneficial if the table was expanded to include other information such as density, atomic number, etc.

    Text Questions:

    1.       Yes.  The information is well organized and easy to follow.

    2.       Yes. Each paragraph has a clear topic.

    3.       None.

    4.       The module was logically organized.
