Thomson depicted the atom as a positively charged "soup" with negatively charged electrons embedded in it
    3. He experimented with a cathode ray tube which is a sealed glass tube with little air in it. This has an electrode at each end one of them is positively charged, and one is negatively charged. When a high-voltage electric current is applied, it creates a cathode ray. This cathode ray is attracted to the positively charged plate and is repelled by the negatively charged plate.
    4. From his experiment, he concluded that the ray was negatively charged and discovered electrons.]]>     2023-09-27 23:54:00 UTC https://padlet.com/386626/pf0or5jxy8l1rn6b/wish/2723877497     Dalton's Theory 386626 https://padlet.com/386626/pf0or5jxy8l1rn6b/wish/2723893145 1. Atoms cannot be created or destroyed. and are rearranged in chemical reactions.

    3. He bombarded a thin sheet of gold foil with alpha particles. While some passed through the foil with minimal deflection, some did at large angles
    4.He concluded that atoms have a small dense nucleus at the center of them]]>     2023-09-28 00:36:11 UTC https://padlet.com/386626/pf0or5jxy8l1rn6b/wish/2723911195     Bohr's Theory 386626 https://padlet.com/386626/pf0or5jxy8l1rn6b/wish/2723927278 1. electrons move in fixed orbitals and each orbital has a fixed amount of energy

    3. measuring the position of an electron under a gamma-ray microscope
    4 An experimenter cannot know the precise momentum and position of an electron]]>     2023-09-28 01:45:26 UTC https://padlet.com/386626/pf0or5jxy8l1rn6b/wish/2723968041
