Question

Which of the following does not belong to the postulates of Dalton’s atomic theory?

• A. Matter is made up of extremely small particles called atoms
• B. Atoms of different elements are same in all respects i.e. size, shape and mass
• C. Atoms of different elements may combine with each other in fixed ratios to form compounds
• D. Atoms can neither be created nor be destroyed in a chemical reaction

Answer 1

The correct option is B Atoms of different elements are same in all respects i.e. size, shape and mass

Matter is made up of extremely small particles called atoms. Atoms can neither be created nor be destroyed.
Atoms of same elements are same in all respects like size, shape, mass and chemical properties. Atoms of different elements combine with each other in fixed ratios to form compounds.
