Dalton's atomic theory was based on two laws, namely the law of conservation of mass (Lavoisier law) "The total mass of substances before the rction will always equal the total mass of the substances the rction." Legal structure and fixed (Law Prouts). "Comparison of the mass of the elements in a compound always remain".
From both the above laws daltons expressed the opinion:
1. Atoms are the smallest part of the material as it can not be subdivided;
2. Atom is described as a very small solid ball, an element has atoms are identical and differ for different elements;
3. Atoms combine to form compounds with a ratio of integers and simple.
For example, water consists of hydro atoms and oxy atoms;
4. The chemical rction is the separation or amaamation or a rrrangement of atoms, so that atoms can not be crted or destroyed.
