Lots of relevant information which is good, i would probably think about adding more visuals like possible a periodic table with arrows showing the trends.

You could add some links to other modules. Also, maybe you could explain metallic character as a periodic trend (why are some of the elements called poor metals?)

I agree with Kain, if you add a periodic table with arrows showing the trends it will allow the reader to understand the trends that they follow.

This is great! but more pictures and diagrams would be good. the ones you have are a little blurry. including a periodic table would be helpful!

I totally agree with Kain and Parisa, you should try to have periodic table with different colored arrows showing the trend. That would be much better to understand. Matter of fact this picture will pretty much tell everything about the general trends instead of having to read a lot of words. But hey its up to you.

I like how you included the answers to the questions/problems posted. One of the few I've seen. It would be nice to see the actual trend in relation to the table so we can get a visual to remember the trend easier. Also the font is a little on the small side. :)

Should also consider many students are visual learners, thus more diagrams and a picture showing the trends would be beneficial. (color would be preferred)

I needed to delete all figures as there were copyrighted violations there. Contact me about fixing them if you desire.

1.Synopsis: This module was about the periodic trends in regards to transition metals such as ionization energy, metallic properties, and electronegativity. The module noted the filled or unfilled orbital’s relating to each periodic property. Additionally, I learned some key characteristics of transition metals such as their ability to be good conductors of energy, malleable and have metallic luster.
2. Keywords: Transition metals (google), metallic radius (yahoo), magnetism (google).
3. Review Details: The module was interesting but I felt it had some repetitive and unnecessary information. Some of the sentences were fragments and did not have much to do with the topic of Periodic Trends. In the first paragraph, copper is mentioned to allow the usage of electricity in homes as is gold however the relationship between the metals and electricity is not explained, leading to confusion for the reader. Additionally, there were many spelling and grammatical mistakes which can side track the focus of the reader from the substance of the module to the mistakes. The length of the module was neither too long nor too short which makes the module appealing and easy to follow and understand. The format in which different characteristics are broken down also allows for faster comprehension of the material, making it enjoyable. In terms of information, the author could have gone more in depth on each of the characteristics, instead of listing the basics. The diagrams are nice as the readers are able to visually see the trends but one colorful engaging diagram which combines all of the trends would be very helpful to students as it would allow students to compare different characteristics and note the differences.
4. Fix one mistake in the Module: I fixed the spelling and grammatical mistakes under the section: Period trends of Transition Metals.

1.Synopsis: This module covers the scope of periodic table and associated trends. It discusses characteristics of transition metals, ionization energy, electronegativity and bond polarity, electrode potential, and magnetism. Examples are provided to aid with understanding.
2. Keywords: periodic trends (msn), melting points (yahoo), electrode potential (google).
3. Review Details: Module provided illustrations and indicated how those illustrations represent core concepts involving periodic trends. Module advanced into discussing about the sub-topics and told how these sub-topics like transition metals, atomic radius, electronegativity, bond polarity, and magnetism come together as individual pieces to form a whole picture of chemical periodicity and trends in the periodic table. This is a decent module. However, in order to make it better and more understandable, I would recommend adding terminology that related to periodic trends. Once we learn the terms and language of periodic trends, all involved-concepts would come easier and learning would be more enjoyable. Terms like periodic table, periods, groups, atomic number, atomic mass, atomic radius, electronegativity, cations, ions…etc should be clarified and included in the module.
4. Fix one mistake in the Module: I added a few comma here and there and corrected grammatical errors. Errors were minimized.

1. Synopsis: This module includes information about the periodic table and its trends, especially those relating to the transitions metals. It covered ionization energy, electronegativity, and element radius trends.
2. Keywords: ionization energy(google) transition metal trends(yahoo) bond polarity (google)
3. Review Details: This module covered the topic of periodic trends through the use of graphs, examples, and illustration. The illustrations of the periodic trends were very easy to read and understand. I agree with Tuyen that this module could include more term definitions to make the information even more clear. The length is not too short but could still use a bit more information, possibly more detail into the different trends. I felt that in general, a lot of the sentences were confusing to read. I was not quite sure what was trying to be said. There were a few spelling errors that I found, but they were simple typos.
4. I fixed a few typos such as form to from. I also rearranged a few sentences that were confusing.
