Dalton's Atomic Theory
CHXI01:SOME BASIC CONCEPTS OF CHEMISTRY

306607 An important postulate of Dalton’s atomic theory is

1 An atom contains electrons, protons and neutrons
2 All the atoms of an element are not identical
3 Atom can neither be created nor destroyed nor divisible
4 All the elements are available in nature in the form of atoms
CHXI01:SOME BASIC CONCEPTS OF CHEMISTRY

306608 Amongst the following statements, that which was not proposed by Dalton was -

1 All the atoms of a given element have identical properties including identical mass. Atoms of different elements differ in mass
2 When gases combine or reproduced in a chemical reaction they do so in a simple ratio by volume provided all gases are at the same T & P
3 Matter consists of indivisible atoms
4 Chemical reactions involve reorganization of atoms. These are neither created nor destroyed in a chemical reaction.
CHXI01:SOME BASIC CONCEPTS OF CHEMISTRY

306609 The incorrect postulates of the Dalton's atomic theory are :
(A) Atoms of different elements differ in mass.
(B) Matter consists of divisible atoms.
(C) Compounds are formed when atoms of different element combine in a fixed ratio.
(D) All the atoms of given element have different properties including mass.
