-  Dalton said that Atoms of different elements combine to make compounds. 
-  Dalton said that all atoms of the same element were the same. 
- Dalton said that atoms of different elements were different.  ]]> 2020-12-07 02:37:58 UTC https://padlet.com/timejiamonroy/z4bassjiwwcu0o1q/wish/992625283 Thomson timejiamonroy https://padlet.com/timejiamonroy/z4bassjiwwcu0o1q/wish/992646159 - Thomson said in 1897  that atoms had small  particle. 
- Thomson came up with the idea that positive and negative have a equal charge. 
- Thomson said that theirs charged particles inside an atom called electrons.

-  Rutherford said that atoms are mostly empty space.  
- His theory was made in 1911. ]]> 2020-12-07 03:04:37 UTC https://padlet.com/timejiamonroy/z4bassjiwwcu0o1q/wish/992666766 Bohr timejiamonroy https://padlet.com/timejiamonroy/z4bassjiwwcu0o1q/wish/992685301 - Bohr  discovered the Planetary Atomic Model. 
- Bohr theory was made in 1913
- Electrons travel in paths called energy levels.
- The location of an electron depends on how much energy it has. ]]> 2020-12-07 03:16:09 UTC https://padlet.com/timejiamonroy/z4bassjiwwcu0o1q/wish/992685301 Chadwick timejiamonroy https://padlet.com/timejiamonroy/z4bassjiwwcu0o1q/wish/992713903 - Chadwick discovered was on Neutrons.
-  Chadwick said that the Nucleus was made of Protons and Neutrons.
- His theory was made in 1932. ]]> 2020-12-07 03:34:57 UTC https://padlet.com/timejiamonroy/z4bassjiwwcu0o1q/wish/992713903 Schrodinger, Heisenberg, Einstein timejiamonroy https://padlet.com/timejiamonroy/z4bassjiwwcu0o1q/wish/992723199  - Schrodinger, Heisenberg and Einstein discovered that electrons  travel in ever changing path. 
-  They have  a different path every time.
-  They also  discovered that electron clouds. 
- This theory was made in 1925.   ]]> 2020-12-07 03:41:01 UTC https://padlet.com/timejiamonroy/z4bassjiwwcu0o1q/wish/992723199
