Following are the important points in Dalton's atomic theory:
1)Each element is made up of tiny individual particles called atoms.
2)Atoms are invisible, they cannot be created or destroyed.
3)All atoms of each element are identical in every respect.
4)Atoms of one element are different from atoms of any other element.
5)Atoms of one element may combine with other atoms of another elements, usually in the rate of small whole numbers, to form chemical components.
Dalton's model successfully explained important observations such as the law of constant composition. The law makes sense because if a compound always contains the same relative number of atoms, it will always contain the same proportion by mass of the various element.
For example, nitrogen and oxygen might form a compound containing one atom of nitrogen and one atom of oxygen(written NO), and compound containing one atom of nitrogen and two atoms of oxygen thus giving a formation of (NO2)Nitrogen Dioxide.
