John+Dalton

John Dalton [|http://www.rsc.org/chemsoc/timeline//pages/1803.html] [] Summarize his theory of the atom. There are multiple parts to his model of the atom. Explain each and include visuals to help us understand each part.

Dalton believed that atoms could be distinguished by differences in their weights. His theory was proposed in 1803; All matter is composed of atoms, different elements have different types of atoms, chemical reactions occur when atoms are rearranged, and compounds are formed from atoms of the comstituent elements. He made the mistake and the atoms weight were off. Dalton provided logical explanations which leld to more experiments.

Law of Multiple Proportions: When two elments form two different compounds, the mass ratio of the elements in one compound is related to the mass ratio in the other by a small whole number. Everything is ade up of atoms and they can not be destoryed or made just transferd
