All the atoms of a given element are identical in every respect, having the same mass, size and chemical properties. Atoms of different elements differ in mass, size and chemical properties. Chemical combination between two elements consists in the joining together of atoms of these elements to form molecules of compounds. Drawbacks of Dalton's Atomic Theory It is now known that some of the statements of Dalton's Atomic Theory of matter are not exactly corre...
