Question

State the Postulates of Dalton's
Atomic Theory and write its
limitations.

Pls ans with limitations

Answer 1

Explanation:

Atoms can neither be created nor destroyed. Furthermore, atoms cannot be divided into smaller particles. Atoms of different elements can combine with each other in fixed whole-number ratios in order to form compounds. Atoms can be rearranged, combined, or separated in chemical reactions

limitations:

The main drawbacks of Dalton's Atomic Theory are: (i) It could explain the laws of chemical combination by mass but failed to explain the law of gaseous volumes. (ii) It could not explain why atoms of different elements have different masses, sizes, valencies, etc.

Answer 2

Answer:

Explanation:

5 POINTS OR POSTULATES-

1)MATTER IS MADE-UP OF TIMY PARTICLES CALLED ATOMS.

2)ATOMS ARE INDIVISIBLE.

3)ATOMS CANNOT BE CREATED OR DESTROYED.

4)ATOMS OF THE SAME ELEMENT ARE IDENTICAL IN MASS AND OTHER PROPERTIES.

5)ATOMS OF DIFFERENT ELEMENTS DIFFER IN THEIR MASSES AND PROPERTIES.

2LIMITATIONS-

1)ATOM IS DIVISIBLE INTO SUB-ATOMIC PARTICLES-e(electron),p(proton),n(neutron).

2)existence of Isotopes, Isotopes are the atoms of same element having same atomic number and same chemical properties but different mass number.
