1. How he depicted and described the atom
He depicted the atom through his model, the chocolate chip cookie model.
He described the atoms as uniformly packed spheres of positive matter filled with negatively charged electrons.
2. (Picture above)
4. The conclusion is that he discovered the atoms as uniformly packed spheres of positive matter filled with negatively charged electrons.

1. How they depicted / described the atom
Dalton depicted the atom through his Atomic Theory.
He described the atom as things that could be neither created nor destroyed. He described atoms as each having a particular size and mass. He described them as circular solid spheres.
2. (Picture above)
3. The conclusion was that he proved Democritus's atomism as purely theoretical and found out that the atoms are all different, can create different elements, and can be neither created nor destroyed.

1. How he depicted / described the atom
He depicted the atom through an experiment and the Thomson Model.
He described atoms as consisting of largely empty space with a few electrons. He described that there was most of the mass in the center which he named the nucleus.
2. (Picture above)
3. Details of the experiment
He shot small positively charged alpha particles at a sheet of gold foil. The atoms thinly dispersed positive charge would not be enough to deflect the particles in any one place. The effect would have been like a bunch of tennis balls punching through a thin paper screen. Most of the particles passed through but some bounced back. This suggested that the foil was more like a thick net with a very large mesh.
4. The conclusion is that atoms consisted largely of empty space with a few electrons and most of the mass was concentrated in the center.

1. How he depicted / described the atom
He depicted the atom through his planetary model and experiments.
He described the atom as electrons behaving simultaneously like waves and not being confined to a particular point in space.
2. (Photo above)
4. The conclusion is that electrons are not discrete particles, instead they simultaneously behave like waves that aren't confined to a particular point in space.

1. How he depicted / described the atom
He depicted the atom through his uncertainty principle.
He described the atom as electrons moving around the atom but within a range of possible locations because it was impossible to determine both the exact position and speed of electrons.
2. (Picture above)
4. the conclusion is that it's impossible to determine both the exact position and speed of electrons as they move around an atom. Electrons can't be pinpointed but they exist within a range of possible locations.
