Unknown when the theory was developed.

He discovered this in 1911 with his gold-foil experiment. This discovery led to scientists realizing that an atom wasn't just one particle, it was made up of multi sub-atomic particles. They discovered this at the University of Manchester.]]> 2017-10-05 12:42:56 UTC https://padlet.com/maxisnotfast/y03uqzw0tfhi/wish/194269346 maxisnotfast https://padlet.com/maxisnotfast/y03uqzw0tfhi/wish/197604832 In 1926, Erwin used math to be able to almost calculate the chances of finding an electron in a certain place. The model is known as the quantum mechanical model.  This was discovered in Germany. ]]> 2017-10-17 00:09:11 UTC https://padlet.com/maxisnotfast/y03uqzw0tfhi/wish/197604832 maxisnotfast https://padlet.com/maxisnotfast/y03uqzw0tfhi/wish/197607546 John Dalton was an English chemist born in 1766. He slightly expanded upon Democritus's theory, saying that everything was made of atoms which are indivisible. He also said that all atoms of the same element are identical in mass and properties.  ]]> 2017-10-17 00:27:38 UTC https://padlet.com/maxisnotfast/y03uqzw0tfhi/wish/197607546 maxisnotfast https://padlet.com/maxisnotfast/y03uqzw0tfhi/wish/197608650 In 1897 Thomson discovered electrons. He discovered electrons using a cathode ray. After discovering this, he realized that the model did not allow negative / positive molecules. He then created his own model similar to plum pudding to allow this.]]> 2017-10-17 00:35:46 UTC https://padlet.com/maxisnotfast/y03uqzw0tfhi/wish/197608650 maxisnotfast https://padlet.com/maxisnotfast/y03uqzw0tfhi/wish/197611381 Bohr's model shows the atom as a nucleus with electrons orbiting in circles around the nucleus. He, with the help of Rutherford, created this model in 1913. ]]> 2017-10-17 00:53:19 UTC https://padlet.com/maxisnotfast/y03uqzw0tfhi/wish/197611381
