He also discovered the protons and the nucleus. ]]> 2022-05-04 16:55:41 UTC https://padlet.com/ardapaksoy3001_2/e91o21prc5jou9cc/wish/2170264882 ardapaksoy3001_2 https://padlet.com/ardapaksoy3001_2/e91o21prc5jou9cc/wish/2170265554 He proposed that electrons move around the nucleus in specific layers, or shells and he improved on Rutherford's model.]]> 2022-05-04 16:56:08 UTC https://padlet.com/ardapaksoy3001_2/e91o21prc5jou9cc/wish/2170265554 ardapaksoy3001_2 https://padlet.com/ardapaksoy3001_2/e91o21prc5jou9cc/wish/2170267270 Working with Rutherford, he discovered particles with no charge; these particles were called as neutrons.]]> 2022-05-04 16:57:11 UTC https://padlet.com/ardapaksoy3001_2/e91o21prc5jou9cc/wish/2170267270 ardapaksoy3001_2 https://padlet.com/ardapaksoy3001_2/e91o21prc5jou9cc/wish/2170269222 Work done since 1920 changed the model, the new model has electrons moving around the nucleus in the cloud.]]> 2022-05-04 16:58:31 UTC https://padlet.com/ardapaksoy3001_2/e91o21prc5jou9cc/wish/2170269222
