His conclusion was that the different compounds were combinations of atoms of different elements, that has a particular size and mass. It could not be created nor destroyed. ]]> 2023-09-28 03:05:06 UTC https://padlet.com/3862482/wtkkr6jybs57bgb1/wish/2724034066 3862482 https://padlet.com/3862482/wtkkr6jybs57bgb1/wish/2724038695 He depicted atoms to be uniformly packed spheres of positive matter and filled with negatively charged electrons. Thompson also discovered the electron. ]]> 2023-09-28 03:10:32 UTC https://padlet.com/3862482/wtkkr6jybs57bgb1/wish/2724038695 3862482 https://padlet.com/3862482/wtkkr6jybs57bgb1/wish/2724044400 He described atoms as a big fish net with large gaps for the atom particles to pass through, while some will bounce back. He concluded that atoms consisted largely of empty space with only a few electrons. He stated how most of the mass was concentrated in the center, known as the nucleus. ]]> 2023-09-28 03:17:26 UTC https://padlet.com/3862482/wtkkr6jybs57bgb1/wish/2724044400 3862482 https://padlet.com/3862482/wtkkr6jybs57bgb1/wish/2724048295 He expanded on Rutherford's work. He depicted that electrons orbit the nucleus at fixed energies and distances. He states that they are able to jump from one level to another but not exist in the space between. It was later on shown that electrons move in a wave like pattern. ]]> 2023-09-28 03:23:12 UTC https://padlet.com/3862482/wtkkr6jybs57bgb1/wish/2724048295 3862482 https://padlet.com/3862482/wtkkr6jybs57bgb1/wish/2724052084 Heisenberg stated that it was impossible to know the exact position and speed of electrons as they moved around an atom. His idea that electrons cannot be pinpointed but exist within a range of possible locations contributed to the now quantum model of the atom. ]]> 2023-09-28 03:28:55 UTC https://padlet.com/3862482/wtkkr6jybs57bgb1/wish/2724052084
