Final answer:
The statement 'Atoms react as per their valence electrons' does not belong to Dalton's Atomic Theory. Dalton's theory doesn't mention anything about atoms reacting according to their valence electrons. This concept is part of later development in atomic structure and chemistry.
Step-by-step explanation:
The statement which does not belong to Dalton's theory is 'Atoms react as per their valence electrons.'. This assumption isn't part of Dalton's postulates. Dalton's Atomic Theory consists of several important aspects:
- All matter is made of atoms. Atoms are indivisible and indestructible.
- All atoms of a given element are identical in mass and properties.
- Compounds are formed by a combination of two or more different kinds of atoms.
- A chemical reaction is a rearrangement of atoms.
However, it doesn't mention anywhere about atoms reacting according to their valence electrons. This concept came into existence later with the development of the atomic structure model, which revealed more about the inner structure of atoms.
