Question

name the main postulates of Dalton atomic theory and what are the limitations

Answer 1

Postulates
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.

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.
