Dalton wondered why the heavier and lighter gases in the atmosphere did not separate as oil and water do. He finally concluded that the constituent【S1】______ must exist in the form of【S2】______ particles or atoms and that these must be completely mixed together in the【S3】______ . This threw a new light in the laws of definite proportions. It was only necessary to suppose that the atoms could combine into small groups of uniform【S4】______ and so form more complex substance; thus the mystery of this law was【S5】______ . Dalton suggested, for example, that carbon monoxide is formed by the one with one【S6】______ of atoms of carbon and oxygen, while carbon dioxide results from a single【S7】______ of carbon uniting with two atoms of oxygen. Assuming this to be true, then the definite proportions of Prout’s law (for all chemical compounds the different constituents【S8】______ enter in unvarying proportions) would naturally【S9】______ the relative weights of the many【S10】______ kinds of atoms.
