Question

give the postulation of dalton's atomic theory

Answer 1

1.atom can neither be created nor destroyed
2.atom is the smallest particle which takes part in chemical reaction.
3.atoms of same elements combine together to form compounds.
4.when atoms of different elements combine together to form compounds they do so in ratio of whole number such as 1:1 ,2:1,2:3
5.atoms of same elements are identical in all respects.
6.atoms of different elements have different size and masses also possess different properties

Answer 2

Postulations of Dalton's atomic theory:

1. All matter consists of indivisible particles called atoms.
2. Atoms of the same element are similar in shape and mass, but differ from the atoms of other elements.
3. Atoms cannot be created or destroyed.
4. Atoms of different elements may combine with each other in a fixed, simple, whole number ratios to form compound atoms.
5. Atoms of same element can combine in more than one ratio to form two or more compounds.
6. The atom is the smallest unit of matter that can take part in a chemical reaction.
