IS JOHN DALTON THE REAL DEVOLOPER OF ATOMIC THEORY |
Atomic theory proposed by John Dalton Dalton's theory was based on the premise that the atoms of different elements could be distinguished by differences in their weights. He stated his theory as: All matter is composed of atoms Atoms cannot be made or destroyed All atoms of the same element are identical Different elements have different types of atoms Chemical reactions occur when atoms are rearranged Compounds are formed from atoms of the constituent elements. |
