Thomson described atoms as uniformly packed spheres of positive matter filled with negatively charged electrons. They also referred to this as the chocolate chip cookie atom.

    3. There were no details mentioned of his experiments in the video.

    4. No conclusion was said in the video, however, when researched it is found that he concluded that all atoms contain tiny negatively charged electrons.]]>     2023-09-27 00:31:48 UTC https://padlet.com/4148881/6klkdovo609hws1r/wish/2722131848     Dalton - Introducing the Atomic Theory 4148881 https://padlet.com/4148881/6klkdovo609hws1r/wish/2722138742 1. Dalton described how common substances always broke down into the same elements in the same proportions.

    2. The sketch is attached at the top.

    3. There were no details mentioned of his experiments in the video.

    4. Dalton concluded that the various compounds were combinations of atoms of different elements. Each being a certain mass and size that couldn't be created or destroyed.]]>     2023-09-27 00:36:57 UTC https://padlet.com/4148881/6klkdovo609hws1r/wish/2722138742     Rutherford - The Father of the Nuclear Age 4148881 https://padlet.com/4148881/6klkdovo609hws1r/wish/2722157671 1. Rutherford described the atom, having a tiny, dense, and positively charged core called the nucleus. He also said that negatively charged electrons circulated around the nucleus.

    2. The sketch is attached at the top.

    3. When Rutherford was studying the effects of x-rays on gases, he decided to try and investigate atoms more closely by shooting tiny positively charged alpha particles at a sheet of gold foil. When he did this experiment, the atoms thinly dispersed, the positive charge wouldn't be enough to deflect the particles in one place. While most of the particles did pass through, some bounced back.

    4. After this experiment, Rutherford concluded that atoms consisted of largely empty space with just a few electrons, while most of the mass was concentrated in the center, which he termed the nucleus. ]]>     2023-09-27 00:50:26 UTC https://padlet.com/4148881/6klkdovo609hws1r/wish/2722157671     Bohr - Investigating Atomic Structure 4148881 https://padlet.com/4148881/6klkdovo609hws1r/wish/2722170786 1. Bohr explained that electrons orbit the nucleus at fixed energies and densities, able to jump from 1 level to another, but not to exist in the space between.

    2. The sketch is attached at the top.

    3. Some experiments that Bohr did showed that rather than simply being describe particles, electrons also behaved like waves, not being confined to a particular point in space.

    4. No conclusion was said in the video, however, when researched it is found that he concluded that the electron would have a larger amount of energy if it were located away from the nucleus.]]>     2023-09-27 01:00:52 UTC https://padlet.com/4148881/6klkdovo609hws1r/wish/2722170786     Heisenberg - Creator of the Uncertainty Principal 4148881 https://padlet.com/4148881/6klkdovo609hws1r/wish/2722176661 1. He described that the electrons were unpredictable, and you couldn't pinpoint the exact value, position, or speed of it. This is also how he introduces his uncertainty principal in the electron orbitals that surround the nucleus.

    2.  The sketch is attached at the top.

    3.      There were no details mentioned of his experiments in the video.

    4    . Heisenberg concluded that it was impossible to determine both the exact position and speed of the electrons as they moved around an atom.
