Dalton states how common substances always break down into the same elements in the same proportions. The various compounds were different elements with different mass and size. 
    2. 
    3. There weren't any details of the experiment but included that he lived modestly until the end of his days.
    4.  The conclusion is that many substances broke down into elements that could neither be created nor destroyed. ]]>     2023-09-27 05:37:58 UTC https://padlet.com/398109/kzehpy92rsik6oot/wish/2722514153     Thomson 398109 https://padlet.com/398109/kzehpy92rsik6oot/wish/2722518878 1. He showed atoms as uniformly packed spheres of positive matter filled with negatively charged electrons.
    2.
    3. He didn't talk about his experiment. 
    4. He discovered the electron and won a Nobel prize for the electron discovery.]]>     2023-09-27 05:42:57 UTC https://padlet.com/398109/kzehpy92rsik6oot/wish/2722518878     Rutherford 398109 https://padlet.com/398109/kzehpy92rsik6oot/wish/2722526936 1. He studied atoms more closely by shooting small positively charged alpha particles at a sheet of gold foil. The atoms thinly dispersed positive charge would not be enough to deflect the particles in any one place. 
    2.
    3. The effect would be like a bunch of tennis balls punching through a thin paper screen. The foil was more like a thick net with very large mesh because the particles would bounce back.
    4. He concluded that the atoms consisted largely of empty space with just some electrons. While most of the mass was in the nucules. ]]>     2023-09-27 05:51:15 UTC https://padlet.com/398109/kzehpy92rsik6oot/wish/2722526936     Bohr 398109 https://padlet.com/398109/kzehpy92rsik6oot/wish/2722532498 1. He focused on the electrons orbiting the nucleus at fixed energies and distances. They were able to jump from one to another but did not exist in the space between them. 
    2.
    3. The model took center stage but had complications. It showed that rather than being discrete particles, they behaved like waves instead of being confined in a space.
    4. The conclusion is that is behaved in waves instead of in a confined space so his experiment had many complications.]]>     2023-09-27 05:56:43 UTC https://padlet.com/398109/kzehpy92rsik6oot/wish/2722532498     Heisenberg 398109 https://padlet.com/398109/kzehpy92rsik6oot/wish/2722537255 1. It was impossible to determine the exact speed and position of electrons as they moved around an atom.
    2.
    3. He did not say details of experiment.
    4. Electrons cannot be pinpointed but exist in a range of possible locations which gave rise to the current quantum model of an atom.]]>     2023-09-27 06:01:35 UTC https://padlet.com/398109/kzehpy92rsik6oot/wish/2722537255
