Dalton's Atomic Theory

John Dalton's atomic theory stated that matter is made up of atoms that are indivisible and indestructible. All atoms of an element are identical. Atoms of different elements have different weights and different chemical properties. Atoms of different elements combine in simple whole numbers to form compounds. Atoms cannot be created or destroyed. When a compound decomposes, the atoms are recovered and unchanged.
