Chase and Harry

Hi Chase, i'm Harry, i live in Naples, Florida. I skateboard, play guitar, and play Xbox live. I think we should do one of these models of the atoms, http://wind.cc.whecn.edu/~mechalke/chapter5/Chapter5.htm. The thomson model on the page looks easy enough. Thomson Model of the Atom

Associates: Your assigned atomic model is: Thomson Model
HI Harry I'm Chase. I'm from Harwood, Texas. I like to watch sports and play xbox live. I like that model it seems we could do that one pretty easily. so JJ Thompson discovered the electron, that must be his sigificance.

Here is the Atomic model theory for the Thomson atomic model. His next statement on the structure of the atom comes in a 1904 article. The first half of the article is filled with detailed calculations about the stability of corpuscles moving about in a positive environment. In fact, Thomson is only able to make calculations where all the corpuscles are limited to roatating in a ring. Moving from ring to sphere proves too difficult a challenge. Here is a quote from the 1904 article:
 * Thomson's Mature Model**

We suppose that the atom consists of a number of corpuscles moving about in a sphere of uniform positive electrification. . . . That seems pretty straighforward, but the problem will soon become the electrons and their mass. By the way, this is often referred to as Thomson's "plum pudding model," where the pudding represents the sphere of positive electricity and the bits of plum scattered in the pudding are the electrons. The ChemTeam likes to call it the "blueberry muffin" model. All those round little blueberries surrounded by the bread of the muffin. Ummmm, good. Some butter on top of a muffin hot from the oven and some nice, COLD milk. Oh my. You can read more of Thomson's 1904 article in the [|classic papers section.] However, not everyone is convinced this is the right answer. Savante Arrhenius (the 1903 Nobel Prize winner in Chemistry) had this to say about Thomson's model in 1907:

"This conception has hitherto remained only a formal one, and has led to no new results." Arrhenius goes on to [|several criticisms] of the Thomson Model. Before leaving this topic, I want to make a point about how the Thomson Model is presented today. Sometimes teachers, and even textbooks, will represent the Thomson Model as a mixture of protons and electrons, like on the right-hand side of this image: Make sure you have the correct idea firmly in mind. The Thomson Model has negative partices (electrons) and a sphere of positive charge. There are NO protons in the Thomson Model of the atoms. Be careful, a teacher might try to trip you up on a test question. (Those teachers sure are evil, aren't they??) The Thomson Model will hold sway for a few years, until Ernest Rutherford announces the nuclear model of the atom in 1911. This tutorial: [|A Brief History of Rutherford's Experiment] starts the story. Interest in the Thomson Model fell off rapidly after 1911, although in 1914 and 1915 attempts were made to resurrect it. These efforts came to nothing and the Thomson Model assumed its place in history as the first modern attempt to construct a theory of atomic structure.

I HAVE READ OVER THE ATOMIC THEORY ABOVE AND I AGREE WITH IT AND I BELIEVE WE SHOULD USE IT IN OUR PROJECT. (p.s. i do have one piece of gum left.)
