You have seen how different atomic models have been proposed over the years and how the structure of each model evolved through the work of different scientists. In this activity, you will explore a simulation to see how each atomic model differs from the others. This simulation enables you to test how each atomic model behaves when light particles are passed through the atoms and to compare your observations with real experimental results. However, for this activity, you’ll just be focusing on looking at the structure of each model. Part A Click the prediction tab and check the first model for the atom, the Billiard Ball. Who suggested this model and what were his conclusions about the structure of an atom? The answer is: This model was suggested by Dalton. He concluded that the atom is a solid, spherical object that is indivisible and indestructible. Atoms of a given element are identical but differ from the atoms of other elements.

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
