Various compounds were a combination of atoms of different elements, each of a particular size and mass. They could not be created or destroyed.]]> 2023-09-26 21:46:58 UTC https://padlet.com/3860181/dc3b4p108ho2f49v/wish/2722005830 Theory three: J.J. Thompson's 3860181 https://padlet.com/3860181/dc3b4p108ho2f49v/wish/2722012757 -He showed atoms as uniformly packed spheres of positive matter and filled with negatively charged electrons.]]> 2023-09-26 21:57:16 UTC https://padlet.com/3860181/dc3b4p108ho2f49v/wish/2722012757 Theory four: Ernest Rutherford 3860181 https://padlet.com/3860181/dc3b4p108ho2f49v/wish/2722017570 - He studied atoms by shooting small, positively charged alpha particles at a sheet of gold foil.
    - The atom’s thinly dispersed positive charge would not be enough to deflect the particles in any one place.  Effect being basically a bunch of tennis balls punching through a thin paper screen.  Some particles bounced back however rather than go through.  This suggested the “foil” was more like a thick net with very big mesh. 
    - Atoms consisted of mostly empty space with just a few electrons, while most mass is concentrated at the center or the nucleus. The alpha particles passed through the gaps but bounced back from the dense, positively charged nucleus. ]]>     2023-09-26 22:05:08 UTC https://padlet.com/3860181/dc3b4p108ho2f49v/wish/2722017570     Theory five: Neils Bohr 3860181 https://padlet.com/3860181/dc3b4p108ho2f49v/wish/2722021746 -Believed that electrons orbited a nucleus at fixed energies and distances. Able to jump from one level to another but not to exist in the space in between. Electrons simultaneously behaved like waves, not being confined to a particular point in space.]]> 2023-09-26 22:12:21 UTC https://padlet.com/3860181/dc3b4p108ho2f49v/wish/2722021746 Theory one: Werner Heisenberg 3860181 https://padlet.com/3860181/dc3b4p108ho2f49v/wish/2722023596 - He believed it was impossible to determine both the exact position of speed of electrons as they moved around an atom. ]]> 2023-09-26 22:15:20 UTC https://padlet.com/3860181/dc3b4p108ho2f49v/wish/2722023596
