Which statement(s) is/are CORRECT regarding Dalton’s Atomic theory?I....
Understanding Dalton’s Atomic Theory
Dalton's Atomic Theory is a foundational concept in chemistry that explains the nature of matter. Let's analyze the given statements to determine their correctness.
Statement I: All matters are made of very tiny particles.
- This statement is correct. Dalton proposed that all matter consists of indivisible atoms, which are the smallest units of matter.
Statement II: Atoms of different elements have different masses and chemical properties.
- This statement is also correct. Dalton asserted that each element is characterized by its unique atoms, which differ in mass and properties, leading to distinct chemical behaviors.
Statement III: The relative number of atoms is variable in any compound.
- This statement is incorrect. Dalton's theory posits that a compound is composed of atoms in a fixed ratio. For example, water (H2O) always contains two hydrogen atoms and one oxygen atom in a constant ratio, which contradicts the idea of variability in the number of atoms.
Conclusion:
- Based on the analysis, only statements I and II are correct. Statement III misrepresents Dalton’s view on the composition of compounds. Therefore, the correct answer is option A (Only I and II).
