According to Dalton's Atomic theory atoms of one element can combine with atoms of another element to form compounds - new complex particles. In a given compound however the different types of atoms are always present in the same relative numbers. Dalton's atomic theory states that all matter is made of small particles called atoms. But he wrongly assumed that atoms cannot be divided. In the late nineteenth century, it was proved that atom can be further divided into three subatomic particles called electron, proton and neutron.
