Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged "soup.". Again a very simple model, and very inaccurate.]]> 2023-10-03 13:29:22 UTC https://padlet.com/abdullaha50/zzk0rsoy0v62je5z/wish/2730254434 abdullaha50 https://padlet.com/abdullaha50/zzk0rsoy0v62je5z/wish/2730260205 Rutherford's gold foil experiment showed that the atom is mostly empty space with a tiny, dense, positively-charged nucleus. Based on these results, Rutherford proposed the nuclear model of the atom. This was much more accurate than previous models and showed how a atom would work but it was very complex looking and confusing.]]> 2023-10-03 13:32:42 UTC https://padlet.com/abdullaha50/zzk0rsoy0v62je5z/wish/2730260205 abdullaha50 https://padlet.com/abdullaha50/zzk0rsoy0v62je5z/wish/2730264346 n 1913, Neils Bohr, a student of Rutherford 's, developed a new model of the atom. He proposed that electrons are arranged in concentric circular orbits around the nucleus. This model is patterned on the solar system and is known as the planetary model. It is much more simple and easy to understand while highlighting how electrons work.]]> 2023-10-03 13:34:51 UTC https://padlet.com/abdullaha50/zzk0rsoy0v62je5z/wish/2730264346 abdullaha50 https://padlet.com/abdullaha50/zzk0rsoy0v62je5z/wish/2730270148 A powerful model of the atom was developed by Erwin Schrödinger in 1926. Schrödinger combined the equations for the behavior of waves with the de Broglie equation to generate a mathematical model for the distribution of electrons in an atom. This was a way more comprehensive model and used math as well to be created, it also showed more about the randomness of electrons and how a atom was really arranged. ]]> 2023-10-03 13:37:54 UTC https://padlet.com/abdullaha50/zzk0rsoy0v62je5z/wish/2730270148
