Which of the following are true according to Dalton’s Atomic Theory?
(i) Atoms can neither be created nor destroyed in a chemical reaction.
(ii) Atoms of different elements have different masses and chemical properties.
(iii) Atoms can be broken down into smaller parts like Protons,Electons And Neutons .
(iv) Atoms of an element have variable chemical properties depending on the Chemical reactions
(v) The relative number and kinds of atoms vary in a given compound.
(vi) Atoms combine in the ratio of small whole numbers to form Compounds.

(vi) Atoms combine in the ratio of small whole numbers to form Compounds.
The correct option is C i, ii, vi
Statements (i, ii, vi) are direct postulates of Dalton’s Theory.
Atoms are indivisible according to Dalton, so statement (iii) is wrong.
Atoms of given element are identical in mass and chemical properties, so statement (ii) is correct
The relative number and kinds of atoms are constant in a given Compound. So the statement (v) is false.
