Which of the following is not a postulate of Dalton's Atomic Theory?
Options:
Answer:
Solution:
Explain the question : Identify the statement not from Dalton's theory.
Concept : This question is based on postulates of Dalton's atomic theory.
Solution : Dalton's theory was centered on the "atom" as the fundamental, indivisible particle of matter. His postulates stated that atoms are the smallest particles in reactions (option 2) and that they combine in simple whole-number ratios to form "compound atoms" (options 3 & 4). The concept and term "molecule" as a distinct particle (especially for elements like or ) were introduced later by avogadro. Dalton's theory did not define matter as being made of "atoms or molecules"; it simply stated it was made of atoms.
Final answer : A
