Atomic Mass :: essays research papers

Laboratory Write-UpThe game in which we participated simulates the former(a) efforts of scientists because they had very little to work with. They too had to guess the size and organise of the atom. In 1911, Rutherford conducted a series of experiments in which he bombarded a put in of gold foil with positively charged alpha particles emitted by hot material. Most of the particles passed through the foil undisturbed, suggesting that the foil was made up mostly of fatuous space rather than of a sheet of solid atoms. just about alpha particles, however, "bounced back," indicating the presence of solid matter. Atomic particles, Rutherfords work showed, consisted primarily of empty space surrounding a well-defined central core called a magnetic core. The game portrays the marbles as the alpha beams that bounce off the foam cores. The foam cores represent the karyon, and the empty space shows how little space the nucleus genuinely takes up. The game we played can be diff erent than what Rutherford experimented with is because the nucleus is much smaller than actually in the game. The foam wasnt up to now in proportion with the size of the space used for the game. Early, atomic scientists actually did not have the prospect of just peeking under the board to pull in the shape. They had to go with the results that they had. Thats why it was so important for them to be hairsplitting because if they did anything wrong then this would invalidate their research. They needed to be real small because they were not as fortunate as scientists today who have engineering to back them up. Scientists today do not necessarily have the opportunity to just peak under the board to obtain results.
