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.

In 1803 Dalton stated in a lecture to the Royal Institution, the Atomic theory. The theory stated that all elements can be distinguished differently by their weights. It also proposed 6 basic ideas. 1) All matter is composed of atoms. 2) Atoms cannot be made or destroyed. 3) All atoms of the same element are identical. 4) Different elements have different types of atoms. 5) Chemical reactions occur when atoms are rearranged. 6) Conpounds are formed from atoms of the constutuent elements

Law of Multiple Proportions- when elements combine to form compounds they do so in whole number ratios.

Dalton did work with the pressures and weights of many different gasses which led him to believe that their properties might depend on little particles (atoms)

Pictures of Dalton's model of atom basically whats happening is dalton said that combing the oxygen and hydrogen together could produce the red&blue, which represents h2o
