Question

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

A. Atoms cannot be created or destroyed

B. Atoms are tiny invisible particles

C. Atoms combine in complex fraction ratios.

D. All the atoms of a particular element have identical properties

​

Answer 1

Explanation:

Postulates of Dalton's atomic theory:

All matter consists of indivisible particles called atoms.

Atoms of the same elements are similar in shape and mass but differ from the atoms of other elements.

Atoms cannot be created or destroyed.

Atoms of different elements may combine with each other in a fixed, simple, whole number ratios to form compound atoms.

The atom is the smallest unit of matter that can take part in a chemical reaction.

Answer 2

Answer:

Atoms of the same elements are similar in shape and mass but differ from the atoms of other elements. Atoms cannot be created or destroyed. Atoms of different elements may combine with each other in a fixed, simple, whole number ratios to form compound atoms.
