Question

Give two drawbacks of Dalton’s atomic theory.

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.

Drawbacks of Dalton's atomic 

Answer 2

hello there !!

⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐

Dalton’s atomic theory suffered from the following drawbacks:

(i) It failed to explain how and why atoms of different elements combine together to form a new ‘group of atoms’.

(ii) It failed to explain how atoms of different elements differ from each other i.e the structure of atom was unknown.

(iii) It failed to explain the nature of the binding forces between different atoms in a molecule.

(iv) According to Dalton, an atom is indivisible, whereas, it can be divided into sub- atomic particles- electrons, protons and neutrons.

(v) Atoms of the same element can differ from each other.Example – isotopes (atoms of the same element with different masses)

(vi) Atoms of different elements can have same masses (isobars).

u can write any 2 drawbacks from the above.
:) hope that helpes !!
