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. He started his theory in 1803. Dalton rationalised the various laws of chemical combination. The theory of the atom waqs baseed on the premis that the atoms of different elements could be disyingushed

Dalton theory was about different elements by differences in their weights. Dalton made the law of multiple proportions which was when elements combine to form compounds they do so in whole number ratios. the multiple parts are that if the mass of the first element is constant the second elements masses would be in a whole number.

He came up with, All matter is composed of atoms. All atoms cannot be made of be destroyed. All atoms of the same element are identical. A different element have different atoms. Chemical reactions occur when atoms are rearranged. Compounds are formed from atoms of the constituent elements. [] he came uo with atoms cant be made or destroyed. all atoms of the same element are identical different elements have different types of atoms.
