Synopsis: Covalent bonds are formed when electrons are shared. They can be represented by Lewis dot structures. Every electron wants to have 8 valence electrons, so they achieve that by sharing with other atoms. A single bond shares one pair of electrons, a double 2, and a triple 3. A single bond is the most stable even though a double bond is stronger. Polar bonds dont share the electrons evenly, nonpolar bonds do.
Keywords: Covalent bonds, Polar/Nonpolar, single/double/triple bonds
Details: Overall I thought that it was really good, and I really liked the visuals. It might be helpful to include a few more examples of the different topics so that it is clear how different elements and compounds are affected. On your polar bond visual you showed the Hydrogen donating its electron, which is kind of misleading because that makes it sound like an ionic bond. I would be sure to point out in the intro that covalent bonding only occurs between 2 nonmetals. I really liked the diversity of your review questions!

Synopsis: A covalent bond is a sharing of electrons between atoms. Atoms want to have a valence shell of eight electrons (octet rule). A single bond consists of a sharing of one pair of electrons, a double bond consists of two pairs, and a triple bond consists of three pairs. In a nonpolar covalent bond, electrons are shared equally unlike a polar covalent bond where electrons are not equally shared.
Keywords: octet rule (Bing), single/double/triple bond (Bing), polar covalent bond (Bing)
Review Details: Your module overall was very good! The information was easy to understand and the links were very helpful. The pictures were very cute and creative but were somewhat hard to see and understand at times. It might help to make them a little larger and give a small explanation of the them beneath your pictures. In your paragraph on the octet rule, you might want to make it clearer that in covalent bonds, atoms share electrons rather than gaining or losing them.

1. Synopsis: A covalent bond is when two nonmetals share electrons. This bonding occurs since atoms want to fill up their outermost orbital with eight valance electrons, reaching a stable state. These bonds can include single, double, or even triple bonds. Polar covalent bonds are bonds that occur when the electrons are not shared an equal manner and Nonpolar covalent bonds are when they are shared equally.
2. Keywords (Google):
a. Covalent Bonds (good)
b. Polar Covalent (good)
c. Nonpolar Covalent (good)
3. Review Details: Overall your module is extremely informative and accurate. Your images and examples make the concept easier to understand. The real-life examples you made in relationship to the different bonds were creative. The practice problems are also really informative since they vary in difficulty level. You may want to change the size of the images since it is difficult to see the picture clearly and include examples with varying elements in order to see how the bonding occurs. edited 00:14, 5 Dec 2009

Thanks for the Feedback.

1. Synopsis: Covalent bonds are formed when electrons are shared between atoms. Nonmetals will make covalent bonds with other nonmetals to gain the stable electron configuration of a noble gas. If two atoms are from the same element, the share is equal which results in nonpolar covalent bond but if the two atoms are from different elements, the share is uneven and the electrons are drawn towards the more electronegative atom which results in a polar covalent bond. Elements need to fill up their valence orbit with eight electrons to become stable as a noble gas (except for hydrogen) because eight electrons are needed to fill s- and p- orbital. In a single bond, two electrons are shared, in a double bond, four electrons are shared, and in a triple bond, six electrons are shared.
2. There are few misspelling in the module like "similiar" needs to be changed to "similar," "fullfill" needs to be changed to "fulfill," "distingished" needs to be changed to "distinguished", number agreement needs to be corrected, spacing between different words like "meaning less" needs to be removed (I corrected this), .and subject-verb agreement needs to be double check in this module.
3. No possible plagiarism in the module.
4. Keyword: Covalent bond (Google), Noble gas configuration (Google), Triple bonds (Bing)
5. The module is very informative with the original figures. The figures were very creative. The picture for the polar bonds was the most effective of all the pictures. So no need to change any of the figures. More problems could have been more effective for the students who read the module so that they can get more practice. So add more problems.

1.A covalent bond involves the sharing of electrons between two atoms. This occurs because the atoms want to fill up their outer shells with electrons and gain stability. Since atoms tend to have different levels of electronegativity, the electrons in the bond are not equally shared. This is known as a polar covalent bond. Nonpolar covalent bonds occur when the electronegativity between the two atoms is the same or similar and electrons are equally shared.
2. There are several grammar mistakes, a few of which I caught. This module is organized fairly well.
3. This module is very informative and the figures are useful and entertaining. I think it would be helpful to note under the Octet Rule section that Hydrogen only needs two electrons to fill its outermost shell (though I think this is mentioned elsewhere in the module). The length of the module is appropriate as everything is explained properly. There are several grammar mistakes. The figures used in this module are informative and are referred to in the text. There are topic sentences, generally definitions, which accurately introduce the ideas in the rest of the paragraph. I also like how this module links to other modules for more in-depth explanations of terms.
4. I corrected several grammar errors, mostly in subject verb agreement, and one tense error.
5. This module passed all three plagiarism site tests. When I compared the module to the text in the textbook, there did not seem to be any apparent plagiarism.
6. The figures passed the tiny eye test.

1. Synopsis: Covalent bonds are different then ionic bonds where electron gains or loss. Covalent bond is an electron that is shared so the electrons can spend some time on one atom and the second atom, so they rotate on both atoms. The reason why these covalent bonds are forming is because they are trying to create a full outer shell for both atoms so that it can be stabled. They are formed between two atoms of similar electro negativity, so they can have an equal pole on the electron.

2. Very Organized and is understandable. From illustration to brief paragraphs. Made it more understandable than the book itself

3. Review Details: Everything was well explained. One thing I do recommend is explaining step by step for the examples. Minor distracting grammatical and spelling error

4. I edited some minor parts. But overall, it was well written

5. Plagiarism Checks: None

6. Figure Check: None

(The synopsis is well said. It gave a direct point of what a covalent bond is from the single, double, and triple bond.)

( I doubled checked myself and it seems like you corrected as well because there was no mistakes)

3. No possible plagiarism in the module.
(agreed)

4. Keyword: Covalent bond (Google), Noble gas configuration (Google), Triple bonds (Bing)
(This is good way to give them the keywords, but it is best to include the definition or better yet the link so that they can compare different sources. For example…..
>Covalent bond= http://en.wikipedia.org/wiki/Covalent_bond
>Noble gad configuration= http://www.answers.com/topic/noble-gas-electron-configuration
>Triple bond= http://en.wikipedia.org/wiki/Triple_bond))

5. The module is very informative with the original figures. The figures were very creative. The picture for the polar bonds was the most effective of all the pictures. So no need to change any of the figures. More problems could have been more effective for the students who read the module so that they can get more practice. So add more problems.

(It is best to describe the different bonds, such as a single bond, double bond, and a triple bond. Let the reader know that there isn’t only one bond, but there is three that has different electrons along the way.)


2. There are several grammar mistakes, a few of which I caught. This module is organized fairly well.
(Were you able to correct the grammar mistakes? If so, you should state that you did or give them an example to correct it)

3. This module is very informative and the figures are useful and entertaining. I think it would be helpful to note under the Octet Rule section that Hydrogen only needs two electrons to fill its outermost shell (though I think this is mentioned elsewhere in the module).

( The hydrogen is mentioned towards the end of the module. It should be at the noncovalent bond.)


4. I corrected several grammar errors, mostly in subject verb agreement, and one tense error.
(You should mention which one you corrected so that they can know for future references.)

5. This module passed all three plagiarism site tests. When I compared the module to the text in the textbook, there did not seem to be any apparent plagiarism.
