    Details - He had experiments with cathode ray tubes which showed that all atoms contain tiny negatively charged subatomic particles or electrons.
    Conclusion - He concluded that the particles making up the rays were 1,000 times lighter than the lightest atom proving that something smaller than atoms existed.]]>     2023-09-26 23:43:23 UTC https://padlet.com/385600/zuo4r26hi7rffjdg/wish/2722078356     Dalton 385600 https://padlet.com/385600/zuo4r26hi7rffjdg/wish/2722083865 Description - a ball-like structure
    Detail - His experiment was based on the assumption that water contains one atom of hydrogen and one atom of oxygen and he used that assumption to calculate the relative atomic weight of hydrogen and oxygen, and other elements. He did this by comparing the masses of compounds they formed.
    Conclusion - He created the periodic table using the information he learned in his experiment.]]>     2023-09-26 23:49:52 UTC https://padlet.com/385600/zuo4r26hi7rffjdg/wish/2722083865     Rutherford 385600 https://padlet.com/385600/zuo4r26hi7rffjdg/wish/2722088876 Description - a miniature solar system with electrons orbiting around a massive nucleus, and as mostly empty space, with the nucleus occupying only a very small part of the atom
    Detail - His experiment with gold foil showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus.
    Conclusion - He concluded that most of the space inside is empty, there is a positive tiny part in the center which contains the whole mass of the atom, and the positive charge must be localized over a very tiny volume of the atom.]]>     2023-09-26 23:55:31 UTC https://padlet.com/385600/zuo4r26hi7rffjdg/wish/2722088876     Bohr 385600 https://padlet.com/385600/zuo4r26hi7rffjdg/wish/2722127678 Description - a small positively charged central nucleus and electrons orbiting in specific fixed distances from the nucleus
    Detail - His experiment was conducted in 1913, where he analyzed the spectral lines of hydrogen, and he observed the colored lines given by a spectroscope.
    Conclusion - He concluded that the electrons were not giving off energy continuously, since the lines were not continuous like a rainbow]]>     2023-09-27 00:28:38 UTC https://padlet.com/385600/zuo4r26hi7rffjdg/wish/2722127678     Heisenberg 385600 https://padlet.com/385600/zuo4r26hi7rffjdg/wish/2722354169 Description - used a matrix-based mathematical model that supported Bohr's model of electrons as particles
    Detail - His experiment formulated quantum mechanics in terms of matrices and discovering the uncertainty principle.
