The theory basically stated that the model stated that matter consists of invisible particles called atoms, He also stated the atoms were interchangeable and homogeneous. The structure of the model was solid. This model was known to be one of the first atom structure]]> 2018-10-08 18:37:54 UTC https://padlet.com/cogginsdelaneyf/sib3nawnp6gb/wish/290445477 cogginsdelaneyf https://padlet.com/cogginsdelaneyf/sib3nawnp6gb/wish/290449751 Dalton founded his Atomic theory in the year 1803 in the United Kingdom. The theory basically stated that all matter was composed of atoms. And elements are made of these extremely small particles. And also the fact atoms cannot be destroyed or subdivided. ]]> 2018-10-08 18:47:37 UTC https://padlet.com/cogginsdelaneyf/sib3nawnp6gb/wish/290449751 cogginsdelaneyf https://padlet.com/cogginsdelaneyf/sib3nawnp6gb/wish/290451705 Mendeleev did not exactly find an atom model but he did make the periodic table. He founded the Table in 1869 in Russia. His Table basically stated that all the chemical elements to be arranged in order of increasing atomic weight. ]]> 2018-10-08 18:51:56 UTC https://padlet.com/cogginsdelaneyf/sib3nawnp6gb/wish/290451705 cogginsdelaneyf https://padlet.com/cogginsdelaneyf/sib3nawnp6gb/wish/290451912 Schrodinger founded his Electron Cloud Model in the year 1887 in Austria. The Model was the quantum mechanical model of an atom. ]]> 2018-10-08 18:52:24 UTC https://padlet.com/cogginsdelaneyf/sib3nawnp6gb/wish/290451912 cogginsdelaneyf https://padlet.com/cogginsdelaneyf/sib3nawnp6gb/wish/290452311 Thompson also used a plum pudding model as his example for his theory. He founded this model in 1897 in England. His theory was that cathode rays in an atom were negatively charged in the atom. ]]> 2018-10-08 18:53:18 UTC https://padlet.com/cogginsdelaneyf/sib3nawnp6gb/wish/290452311 cogginsdelaneyf https://padlet.com/cogginsdelaneyf/sib3nawnp6gb/wish/290452615 In New Zealand in the 1911, Rutherford founded a model that stated that the major portion of an atom is empty space.]]> 2018-10-08 18:54:04 UTC https://padlet.com/cogginsdelaneyf/sib3nawnp6gb/wish/290452615 cogginsdelaneyf https://padlet.com/cogginsdelaneyf/sib3nawnp6gb/wish/290452707 In 1913 in England, Bohr showed in his model that electrons should move around the nucleas but only in prescribed orbits.]]> 2018-10-08 18:54:16 UTC https://padlet.com/cogginsdelaneyf/sib3nawnp6gb/wish/290452707
