What did john dalton state in his atomic theory

The prime points of Dalton's atomic theory are:  

1. All the atoms of an element are the same.  

2. Each and every component comprises atoms that are the undifferentiated building elements of the matter and cannot be destroyed.  

3. The atoms of distinct elements differ in mass and size.  

4. The compounds get generated via distinct whole-number combinations of atoms.  

5. The rearrangement of the atoms in the reactant and the product results because of a chemical reaction.  

the answer is true. hope it .
