Question

give the postulates of dalton's atomic theory,5. How is the sige of an atom indicated

Answer 1

All matter consists of indivisible particles called atoms.

Atoms of the same element 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.

Atoms of same element can combine in more than one ratio to form two or more compounds.

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

Answer 2

Hi


Here is your answer

The main points of Dalton's atomic theory are: Elements are made of extremely small particles called atoms. Atoms of a given element are identical in size, mass and other properties; atomsof different elements differ in size, mass and other properties. Atoms cannot be subdivided, created or destroyed.


I hope this answer helps you
