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

CONCLUSION
He concluded that the various compounds were combinations of atoms of different elements, each a particular size and mass, that could neither be created nor destroyed.

In 1897 Thomson discovered the electron. He showed atoms as uniformly packed spheres of positive matter filled with negative electrons  ]]> 2023-09-28 03:29:51 UTC https://padlet.com/3866091/8nnz3pypvajwkkq0/wish/2724052639 3866091 https://padlet.com/3866091/8nnz3pypvajwkkq0/wish/2724064600 EXPERIMENT
Rutherford shot small positively charged alpha particles at a sheet of gold foil. Most particles went right through the foil but some bounced back.

CONCLUSION
Atoms consist of largely empty space with just a few electrons, while most of the mass is concentrated in the center, also called the nucleus ]]> 2023-09-28 03:49:19 UTC https://padlet.com/3866091/8nnz3pypvajwkkq0/wish/2724064600 3866091 https://padlet.com/3866091/8nnz3pypvajwkkq0/wish/2724070466 HIS DEPICTION OF AN ATOM
He stipulated that electrons orbited the nucleus at fixed energies and distances that are able to jump from one level to another, but not to exist in the space between. ]]> 2023-09-28 03:58:49 UTC https://padlet.com/3866091/8nnz3pypvajwkkq0/wish/2724070466 3866091 https://padlet.com/3866091/8nnz3pypvajwkkq0/wish/2724076394 HIS DEPICTION OF AN ATOM
Electrons cannot be pinpointed but exists within a range of possible locations

CONCLUSION
It is impossible to determine both the exact position and speed of electrons as they moved around an atom. ]]> 2023-09-28 04:09:09 UTC https://padlet.com/3866091/8nnz3pypvajwkkq0/wish/2724076394
