He called these particles "atomos" which is Greek for "indivisible" as a result of his suggestion.]]> 2023-09-26 22:23:05 UTC https://padlet.com/4323171/cw6qmsgivihceuy7/wish/2722028310 John Dalton 4323171 https://padlet.com/4323171/cw6qmsgivihceuy7/wish/2722219908 John Dalton depicted that common substances always broke down into the same elements composing it in the same proportions. He concluded that various compounds were made of atoms of different elements that combined together with each having a specific size and mass that can't be created nor destroyed.]]> 2023-09-27 01:34:16 UTC https://padlet.com/4323171/cw6qmsgivihceuy7/wish/2722219908 J.J. Thompson 4323171 https://padlet.com/4323171/cw6qmsgivihceuy7/wish/2722227482 J.J. Thompson described that atoms are packed spheres of positive matter that are filled with negatively charged electrons after his discovery of electrons.]]> 2023-09-27 01:39:34 UTC https://padlet.com/4323171/cw6qmsgivihceuy7/wish/2722227482 Ernest Rutherford 4323171 https://padlet.com/4323171/cw6qmsgivihceuy7/wish/2722294865 Ernest Rutherford wanted to further research atoms while studying effects from X-rays on gases, so he shot small, positively charged alpha particles at a gold foil sheet and although most particles passed through the sheet, some bounced away from it. So he concluded and illustrated that the atom was a largely empty space with a few electrons and at the center was concentrated mass which he named the nucleus. As many alpha particles passed through the atom's empty space, some bounced from the nucleus at the center.]]> 2023-09-27 02:27:59 UTC https://padlet.com/4323171/cw6qmsgivihceuy7/wish/2722294865 Niels Bohr 4323171 https://padlet.com/4323171/cw6qmsgivihceuy7/wish/2722307301 Niels Bohr added on to Ernest Rutherford's depiction of the atom by suggesting the electrons orbit the nucleus at predetermined energies and distances which can jump from one level to another but not to the space between the orbit.]]> 2023-09-27 02:36:14 UTC https://padlet.com/4323171/cw6qmsgivihceuy7/wish/2722307301
