Bi101 unit 1 discussion post 1
The purpose of this Discussion topic is to not only introduce you to the concepts of Chemical Bonding, but to also ensure that you understand the proper use of resource material in order to avoid Plagiarism. In this class you will be exposed to new concepts and terms, which means you will need to use books and websites to formulate your answers. According to Park University:
“Plagiarism involves the use of quotations without quotation marks, the use of quotations without indication of the source, the use of another’s idea without acknowledging the source, the submission of a paper, laboratory report, project, or class assignment (any portion of such) prepared by another person, or incorrect paraphrasing.”

to give you some help on knowing how I like you to reference discussion assignments and homework responses.
Based on the above information and the course policies outlined in our Syllabus, review the information below and address the questions asked. You will need to read the material carefully and compare it to the source from which it was derived.
According to our book, a chemical bond is an attraction between two atoms resulting from the sharing of outer-shell electrons or the presence of opposite charges on the atoms. The bonded atoms gain complete outer electron shells. There are three main types of chemical bonds, ionic, covalent and hydrogen.
An ionic bond is “a type of chemical bond formed through an electrostatic attraction between two oppositely charged ions. Ionic bonds are formed due to the attraction between an atom that has lost one or more electron (known as a cation) and an atom that has gained one or more electrons (known as an anion). Usually, the cation is a metal atom and the anion is a nonmetal atom.” (Wikipedia)
A covalent bond is a bond that consists of the use of the same electron pairs between atoms. The balance of repulsive and attractive forces among atoms when they both use these electrons is called covalent bonding. For several molecules, these shared electrons permit each atom to get a full outer shell, related to a constant electron configuration. (Wikipedia)
Hydrogen bonds can form when electrons in a covalent bond are unequally shared (= polar covalent bond), such as in a molecule of water. In this case, the oxygen atom holds on to the electrons more than the hydrogen atoms, causing the oxygen atom to become slightly negatively charged and the hydrogen atoms to be slightly positively charge. This results in the attraction between a hydrogen atom in one water molecule and an oxygen atom in a neighboring water molecule; this attraction is called a hydrogen bond (Simon, Dickey and Reece 2013, p 28).

- Evaluate each of the four paragraphs. Do any of them constitute plagiarism according to Park University? If so, why (be specific) and how could you correct the information so that the resource has been used correctly?
- Aside from the issue of plagiarism, based on our course policies, has the information above been used correctly?
- Demonstrate your understanding of chemical bonds by finding and explaining an example of a molecule that contains a covalent bond, one that contains an ionic bond, and one that can form hydrogen bonds. Do NOT use water, ammonia or sodium chloride! However, the examples you use here may be the same as the ones you use in your Unit 1 Homework.
