Jacob and Blake Hi, im Jacob and im from Philly! GO EAGLES!!!! Hey, I am Blake and i live in Sweden! :D :D :D What should we do for our project? I don't know, what do you want to do?

Associates: Your assigned atomic model is: Thomson
__Jacob Stanley__ 1. Good morning Mr. Driggers. I work at the ATM Corporation northeastern regional headquarters in Philadelphia, PY. We have been assigned by our international relations officer, Michelle Cooper, to make a atomic model based on Thomson's model. We have also been requested to make a Microsoft Photo Story 3 movie on it as well. I would love to hear some of your ideas on this project. Since you live in Sweden, it will be difficult to transfer our seperate parts of the project by UPS trancontinental and overseas. Mrs. Cooper says that the company will pay for shipping costs. I would also like you to read through the research below, and tell me what you think about it.

2. The plum pudding model of the atom was proposed by J. J. Thomson, who discovered the electron in 1897. The plum pudding model was proposed in 1904 before the discovery of the atomic nucleus. In this model, the atom is composed of electrons surrounded by a soup of positive charge to balance the electron's negative charge, like negatively-charged "plums" surrounded by positively-charged "pudding". The electrons were thought to be positioned throughout the atom, but with many structures possible for positioning multiple electrons, particularly rotating rings of electrons. Instead of a soup, the atom was also sometimes said to have had a cloud of positive charge. The model was disproved by the 1909 gold foil experiment, which was interpreted by Ernest Rutherford in 1911 to imply a very small nucleus of the atom containing a very high positive charge (enough to balance about 100 electrons in gold), thus leading to the Rutherford model of the atom, and finally to the Antonius Van den Broek suggestion that atomic number **is** nuclear charge. Eventually, by 1913, this work had culminated in the solar-system-like Bohr model of the atom, in which a nucleus containing an atomic number of positive charge is surrounded by an equal number of electrons in orbital shells. In 1897, J.J. Thomson discovered the electron, the first subatomic particle. He also was the first to attempt to incorporate the electron into a structure for the atom. The internal structure of the atom had been a source of speculation for thousands of years. The Greeks taught that the atom was solid, as did Dalton. Although Dalton did allow for the fact that there might be a sub-atomic structure of which he was unaware. Thomson faced two major problems: how to account for the mass of the atom when the electron was only about 1/1000 the mass of the hydrogen atom and how to create a neutral atom when the only particle available was negatively charged.His solution was to rule the scientific world for about a decade and Thomson himself would make a major contribution to undermining his own model.



Good Afternoon Mr Stanley. The research that you posted above is very interesting, and may come in handy while we make our atomic model based on Thomson's. I also have some skills on photo story 3 as well, should you ask. I have found some research about Thomson's atomic model and have posted it below. Since Thomson thought that the structure of an atom looks like raisen bread, maybe we could make a model out of that.

Thomson thought that the structure of an atom looked alot like a peice of raisen bread. Because of this his atomic model is sometimes refered to as the raisen bread model. he predicted that the basic body of an atom is a round object containing negative electrons confined in homogenous jellylike but relatively massive positive charge distribution whose total charge cancels out that of the negaive electrons. The schematic of this model is shown in the following drawing below. Thomsons model is sometimes dubbed a Plum Pudding Model.
