Question:-

Which among the following is not a postulate of Dalton's atomic theory?

• A)Atoms can not be created or destroyed

• B)Atoms of different elements have different sizes, masses and chemical properties

• C) Atoms of same elements can combine in only one ratio to produce more than any one compound

• D) Atoms are very tiny particles which can not be further divided

Answer:-

• Correct Option :- C) Atoms of same elements can combine in only one ratio to produce more than any one compound

Some of the postulates of Dalton's atomic theory:-

• Atoms of different elements can be hold apart by their atomic weight.

• Atoms can neither be created not be destroyed.

• Atoms of a given element have identical mass and chemical properties.

• Atoms of different elements have different masses and chemical properties.

• Atoms of different elements combine in simple integral ratios to form compounds.

• It is the atom in an element that takes part in a chemical reaction.

• All matter is made up of tiny indivisible particles known as atoms.
