Dalton showed that common substances always broke down into the same elements.

3. Various compounds were a mixture of different atoms.
4. Received many honors for his work but lived modestly.]]> 2023-09-28 04:52:00 UTC https://padlet.com/3812192/7aiqbww76t9qz9mb/wish/2724102020 Thompson's Theory 3812192 https://padlet.com/3812192/7aiqbww76t9qz9mb/wish/2724104102 1. He showed atoms as uniformly packed spheres of positive matter filled with negatively charged electrons.
2. Attached
3. Packed spheres of positive charged matter but also contained negatively charged matter.
4. Won a Nobel Prize, didn't stick around for long.]]> 2023-09-28 04:55:28 UTC https://padlet.com/3812192/7aiqbww76t9qz9mb/wish/2724104102 Rutherford's Theory 3812192 https://padlet.com/3812192/7aiqbww76t9qz9mb/wish/2724107451 1. Atoms consisted largely of empty space with just a few electrons, while most of the mass was concentrated in the center, which he termed the nucleus.

3. Mass concentrated in the center, gasses would pass through the center.
4. Rutherford's model would be a step closer to the accurate Atomic Model.

He stipulated that electrons orbit the nucleus at fixed energies and distances, able to jump from one level to another, but not to exist in the space between. 
2. Attached
3. At fixed places, the electrons orbit the matter like planets orbit a star.
4. Yet another small step for the Atomic Theory but not quite it yet.

As electrons circling an atom shift between energy levels, they absorb or release energy in the form of specific wavelengths of light, resulting in all the marvelous colors we see.
2. Attached
3. There are rings that are in motion as well as the electrons orbiting the nucleus in which work together.
4. Overall showed how it was impossible to determine the speed and direction of the atoms.
