where: England
theory: All matter was composed of atoms. The first part of his theory states that all matter is made of atoms, which are indivisible.The second part of the theory says all atoms of a given element are identical in mass and properties. The third part says compounds are combinations of two or more different types of atoms. The fourth part of the theory states that a chemical reaction is a rearrangement of atoms.

where: England
theory: Discovered the electron. He demonstrated that cathode rays were negatively charged.

where: Russia
theory: Periodic law. The statement that the chemical and physical properties of the elements recur periodically when the elements are arranged in the order of their atomic weights.]]> 2018-10-08 13:20:40 UTC https://padlet.com/phillipsemilyj/3gzfmjl5qk89/wish/290282954 phillipsemilyj https://padlet.com/phillipsemilyj/3gzfmjl5qk89/wish/290284146 when: 1911
where: New Zealand
theory: discovered that atoms have a small charged nucleus surrounded by a large empty space, and has tiny circular electrons spinning around it.]]> 2018-10-08 13:22:34 UTC https://padlet.com/phillipsemilyj/3gzfmjl5qk89/wish/290284146 phillipsemilyj https://padlet.com/phillipsemilyj/3gzfmjl5qk89/wish/290285634 when: 1913
where: Denmark
theory: electrons travel in separate orbits around the nucleus and that the number of electrons in the outer orbit determines the properties of an element.]]> 2018-10-08 13:25:29 UTC https://padlet.com/phillipsemilyj/3gzfmjl5qk89/wish/290285634 phillipsemilyj https://padlet.com/phillipsemilyj/3gzfmjl5qk89/wish/290286580 when: 1926
where: Austria
theory: used math equations to describe the likelihood of finding an electron in a certain position.]]> 2018-10-08 13:27:17 UTC https://padlet.com/phillipsemilyj/3gzfmjl5qk89/wish/290286580
