Atomic theory of Dalton's importance is as follows:All matter consists of smallest particles called atoms, which cannot be divided further. Atoms cannot be created or lost. The atoms of the elements of the same type, the same shall. That is, have all the same properties, physical and chemical. The atoms of the elements of the same type have the same weight or mass. A compound formed by the chemical between atoms of different types of element with the atomic number is the ratio of the number of fibres. The atoms of the elements of two or more types can be combined into compounds with more than one ratio to cause more than 1 type of compounds.
