Article Evaluation

Titanium dioxide

"Is everything in the article relevant to the article topic?"

Insofar as I can tell via my initial reading of this article, everything in this article is relevant to the article topic.

"Is the article neutral? Are there any clINtaims, or frames, that appear heavily biased toward a position?"

Yes, this article is neutral. I could not find any argumentative statements that would qualify as setting a position. Most of the article is written in a mix of active and passive voice, in a documentary-esque summarizing style.

"Are there any viewpoints that are overrepresented, or underrepresented?"

As far as I can see, this is not the case here.

"Check a few citations. Do the links work? Does the source support the claims in the article?"

I checked a few citations, most of them worked, but I found one, number 47, that lead to a web page that no longer exists.

"Is each fact referenced with an appropriate, reliable reference? Where does the information come from? Are these neutral sources? If biased, is that biased noted?

Each fact that I reviewed had a clear link to a neutral, unbiased source. The information was source mostly from academic journals, industry sources such as safety information required by law, and the like.

"Is any information out of date? Is anything missing that could be added?"

This article seems to be appropriately up to date. I couldn't find any information that is out of date. The only thing that I found to be missing was a working link for one of the references.

"Check out the talk page of the article. What kinds of conversations, in any, are going on behind the scenes about how to represent this topic?"

There are several conversations going on at once, ranging from the merits of Titanium Dioxide as a material, to the wording used to describe its history and attributes.

"How is this article rated? Is it a part of any WikiProjects?"

This article is rated as a "B Class" article. It is part of three Wikiprojects:

1. WikiProject Food and drink
2. WikiProject Chemistry
3. WikiProject Occupational Safety and Health

"How does the way Wikipedia discusses this topic differ from the way we've talked about it in class?"

There is a lot of informal discussion going on in the talk page. There is a lot of uncertainty surrounding pending edits and a good bit of back and forth between editors, which is something that I was not expecting to be a big part of an article on a ubiquitous material like Titanium Dioxide.

Introduction

An intramolecular force is any force that binds together the atoms making up a molecule or compound, not to be confused with intermolecular forces, which are the forces present between molecules. The subtle difference in the name comes from the Latin roots of English with inter meaning between or among and intra meaning inside. Chemical bonds are considered to be intramolecular forces, for example. These forces are often stronger than intermolecular forces, which are present between atoms or molecules that are not bonded.

Types of Intramolecular Forces

The classical model identifies three main types of chemical bonds: ionic, covalent, and metallic, which are distinguished by the degree of electron sharing between participating atoms. The properties of the bond formed, such as bond length and enthalpy can be predicted by from the properties of constituent atoms, namely electronegativity and electrostatic potential energy. The differences between each type of intramolecular force distinguishes the properties of the polyatomic molecules that are formed from the properties of its constituent atoms.

Hydrogen bonds are an important example of a force that can be either intramolecular or intermolecular

Biochemistry

The alpha helix structure necessary for the stability of DNA is held together by the electrostatic intramolecular forces in the protein.

Intramolecular forces are extremely important in the field of biochemistry, where it comes into play at the most basic levels of biological structures. Intramolecular forces such as disulfide bonds give proteins and DNA their structure. Proteins derive their structure from the intramolecular forces that shape them and hold them together. The main source of structure in these molecules is the interaction between the amino acid residues that form the foundation of proteins. The interactions between residues of the same proteins forms the secondary structure of the protein, allowing for the formation of beta sheets and alpha helices, which are important structures for proteins and in the case of alpha helices, for DNA.
