Conclusion: He concluded that the various compounds were combinations of atoms of different elements, each of a particular size and mass that could never be created or destroyed.]]> 2023-09-27 04:45:27 UTC https://padlet.com/386094/eag03sqnv6m8ydep/wish/2722461092 Thomson's theory 386094 https://padlet.com/386094/eag03sqnv6m8ydep/wish/2722461875 Describing the atom: Uniformly packed spheres of positive matter filled with negatively charged electrons.

Conclusion: Thomson won a Nobel Prize in 1906 for his electron discovery.

The alpha particles pass through the gaps but bounce back from the dense positively charged nucleus.

Experiment: Shot small, positively charged alpha particles at a sheet of gold foil.

Conclusion: Atoms consisted largely of empty space with just a few electrons, while most of the mass was concentrated in the center (the nucleus).

Conclusion: Rather than being discrete particles, electrons simultaneously behaved like waves, not being confined to a particular point in space.

Conclusion: He could only predict where an electron might be at any given time. You cannot know both the position and speed of a particle with perfect accuracy.
