==========================
DRAWBACKS OF DALTON’S ATOMIC THEORY
1)It could not explain the structure of atom.
2) It could not explain the concept of isotopes and isobars.
3) It could not explain how atoms of the different elements are different.
4) It could not explain law of gaseous volumes.
5) It could not explain Berzelius hypothesis.
6) It failed to explain the cause of chemical combinations.
7) It failed to distinction between ultimate particles of an element and a compound.
8) It failed to explain the nature of binding forces between the atoms in a molecule
hope it's help you if u like the answer mark as a brain list
Dalton is a scientist who formulated certain postulates to define structure of atom....
His postulates are:
1.Each element is composed of extremely small particles called atoms.
2.Atoms of all given element are identical,the atoms of different elements are different and have different properties.
3.Atoms are neither created not destroyed in chemical reactions.
4.Compounds are formed when more than one element combine, a given compound always has the same relative number and kind of atoms.
5. When elements combine together they always combine in ratio of whole numbers
6.Atoms of a single element may combine in different ratios when they form more than one compound
7. An atom is the smallest particle that takes part in chemical reaction.
But his theory was discarded due to certain discoveries made later.
Foe ex:The first postulate was discarded when they found sub atomic particles like protons,electrons and neutrons
