Choose the Incorrect Statement about Dalton's Atomic Theory

Updated On: Mar 25, 2026
  • Compounds are formed when atoms of different elements combine in any ratio
  • All the atoms of a given element have identical properties including identical mass
  • Matter consists of indivisible atoms
  • Chemical reactions involve recorganization of atoms
Show Solution

The Correct Option is A

Solution and Explanation

According to Dalton’s Atomic Theory, compounds form when atoms of different elements unite in a constant, simple, whole-number ratio, not any arbitrary ratio. This principle underpins the law of definite proportions. Consequently, statement (1) is inaccurate. The remaining statements accurately depict the indivisible nature of atoms and their role in chemical reactions as per Dalton’s theory.
