During cathode ray tube experiment, a negatively charged particle was discovered by J.J. Thomson. The negative particle was called an electron. Thomson assumed that an electron is two thousand times lighter than a proton and believed that an atom is made up of thousands of electrons. In this atomic structure model, he considered atoms surrounded by a cloud having positive as well as negative charges.   
2. Thomson demonstrated in an experiment that cathode rays were deflected by an electric field. This suggested that cathode rays were composed of negatively charged particles found in all atoms. Thomson concluded that the atom was a positively charged sphere of almost uniform density in which negatively charged particles were embedded. ]]> 2021-09-16 18:14:59 UTC https://padlet.com/kmaloneystem/JJThompson/wish/1746721977 Atiira FaSenntao - 6th Period https://padlet.com/kmaloneystem/JJThompson/wish/1746733041 2021-09-16 18:20:48 UTC https://padlet.com/kmaloneystem/JJThompson/wish/1746733041 Shenlin Buchanan 6th Period https://padlet.com/kmaloneystem/JJThompson/wish/1746735483 2021-09-16 18:22:07 UTC https://padlet.com/kmaloneystem/JJThompson/wish/1746735483 Hailey 6th period https://padlet.com/kmaloneystem/JJThompson/wish/1746737680 2021-09-16 18:23:17 UTC https://padlet.com/kmaloneystem/JJThompson/wish/1746737680 Hailey 6th period https://padlet.com/kmaloneystem/JJThompson/wish/1746743643 Accidentally turned in the wrong one this is right !!]]> 2021-09-16 18:26:25 UTC https://padlet.com/kmaloneystem/JJThompson/wish/1746743643 Robbie Bixler period 6 https://padlet.com/kmaloneystem/JJThompson/wish/1746745046 2021-09-16 18:27:08 UTC https://padlet.com/kmaloneystem/JJThompson/wish/1746745046 Rishi Jeyamurthy 7th Period https://padlet.com/kmaloneystem/JJThompson/wish/1746793404 Source: Crash Course Video]]> 2021-09-16 18:53:23 UTC https://padlet.com/kmaloneystem/JJThompson/wish/1746793404 JJ Thomson https://padlet.com/kmaloneystem/JJThompson/wish/1746798885 Sources: 1.3 Resource Reading Atomic History]]> 2021-09-16 18:56:29 UTC https://padlet.com/kmaloneystem/JJThompson/wish/1746798885 Nazar Khomenko 7th https://padlet.com/kmaloneystem/JJThompson/wish/1746817215 2021-09-16 19:07:43 UTC https://padlet.com/kmaloneystem/JJThompson/wish/1746817215 JJ Thompson https://padlet.com/kmaloneystem/JJThompson/wish/1746819162
