Question

Choose the Incorrect Statement about Dalton's Atomic Theory

• A. Compounds are formed when atoms of different elements combine in any ratio
• B. All the atoms of a given element have identical properties including identical mass
• C. Matter consists of indivisible atoms
• D. Chemical reactions involve recorganization of atoms

Answer 1

Answer: (A)

Compounds are formed when atoms of different elements combine in any ratio

Answer 2

Dalton’s Atomic Theory states that compounds are formed when atoms of different elements combine in a fixed, simple, whole number ratio, not in
any ratio. This forms the basis of the law of definite proportions. Therefore, statement (1) is incorrect. Other statements correctly describe the indivisible nature of atoms and their behavior in chemical reactions according to Dalton’s theory.
