Dalton’s atomic theory is successfully explained by(i) Law of conserva...
Dalton's atomic theory proposed that all matter was composed of atoms, indivisible and indestructible building blocks. While all atoms of an element were identical, different elements had atoms of different sizes and mass. 
Dalton's atomic theory explains:
  1. Law of conservation of mass
  2. Law of constant composition
  3. Law of multiple proportions

Understanding Dalton's Atomic Theory
Dalton's atomic theory is fundamental in the field of chemistry, providing a framework for understanding the composition and behavior of matter. It is supported by various laws that relate to atoms and their interactions.
Supporting Laws
- Law of Conservation of Mass
- States that mass is neither created nor destroyed in a chemical reaction. This supports Dalton’s idea that atoms are indivisible and retain their identity in reactions.
- Law of Constant Composition
- Asserts that a given compound always contains the same proportion of elements by mass. This aligns with Dalton’s theory that compounds are formed from fixed ratios of atoms.
- Law of Multiple Proportions
- Indicates that when two elements form different compounds, the ratios of the masses of the second element that combine with a fixed mass of the first are simple whole numbers. This supports Dalton’s notion of atoms combining in specific ratios.
Non-supporting Law
- Law of Radioactivity
- This law deals with the behavior of unstable nuclei and is not directly related to Dalton's atomic theory, which primarily focuses on the behavior of stable atoms and their combinations.
Conclusion
The correct answer is option 'D' (i), (ii), and (iv) because these laws directly reinforce the principles outlined in Dalton's atomic theory. Each law provides evidence for the existence, behavior, and combination of atoms, while the law of radioactivity is a separate concept that does not pertain to Dalton's foundational ideas.
