WebPart 4: A chemical reaction is a rearrangement of atoms. In the fourth and final part of Dalton's atomic theory, he suggested that chemical reactions don't destroy or create atoms. They merely rearranged the atoms. Using our salt example again, when sodium combines with chlorine to make salt, both the sodium and chlorine atoms still exist. WebAug 3, 2024 · Dalton proposed his atomic theory in 1804. The general tenets of this theory are: All matter is composed of extremely small particles called atoms. Atoms cannot be subdivided, created, or destroyed. Atoms of a given element are identical in size, mass, and other properties. Atoms of different elements differ in size, mass, and other properties.
