He discovered his theory around 400B.C.E. He lived and did most of his work in Greece.]]> 2023-01-31 18:46:54 UTC https://padlet.com/schuylergrahame/jaubm3f31ycwn996/wish/2463521276 John Dalton schuylergrahame https://padlet.com/schuylergrahame/jaubm3f31ycwn996/wish/2464961140 Dalton's atomic theory suggested that all matter was comprised of indivisible and indestructible atoms with distinct masses and properties. He made his discovery in 1803. He was Born in Eaglesfield, United Kingdom]]> 2023-02-01 17:35:01 UTC https://padlet.com/schuylergrahame/jaubm3f31ycwn996/wish/2464961140 Joseph Thomson schuylergrahame https://padlet.com/schuylergrahame/jaubm3f31ycwn996/wish/2464983610 On his return from America, he achieved the most brilliant work of his life – an original study of cathode rays culminating in the discovery of the electron.He made this discovery in 1897.He was born in Manchester, United Kingdom.]]> 2023-02-01 17:49:41 UTC https://padlet.com/schuylergrahame/jaubm3f31ycwn996/wish/2464983610 Ernest Rutherford schuylergrahame https://padlet.com/schuylergrahame/jaubm3f31ycwn996/wish/2464990247 Ernest Rutherford found that the atom is mostly empty space, with nearly all of its mass concentrated in a tiny central nucleus. Ernest rutherford was born in 1871 in New Zealand]]> 2023-02-01 17:53:55 UTC https://padlet.com/schuylergrahame/jaubm3f31ycwn996/wish/2464990247 Erwin Schrodinger schuylergrahame https://padlet.com/schuylergrahame/jaubm3f31ycwn996/wish/2464994698 Erwin Schrödinger theorized that the behavior of electrons within atoms could be explained by treating them mathematically as matter waves. He was born in 1887 in Austria.]]> 2023-02-01 17:56:48 UTC https://padlet.com/schuylergrahame/jaubm3f31ycwn996/wish/2464994698 Bohr developed the Bohr model of the atom, in which he proposed that energy levels of electrons are discrete and that the electrons revolve in stable orbits around the atomic nucleus but can jump from one energy level (or orbit) to another. He was born in 1885 in Denmark. schuylergrahame https://padlet.com/schuylergrahame/jaubm3f31ycwn996/wish/2464996611 2023-02-01 17:58:06 UTC https://padlet.com/schuylergrahame/jaubm3f31ycwn996/wish/2464996611
