• Dalton’s atomic theory proposed that all matter was composed of atoms, indivisible and indestructible building blocks. While all atoms of an element were identical, different elements had atoms of differing size and mass.
• Dalton’s atomic theory also stated that all compounds were composed of combinations of these atoms in defined ratios.
• Dalton also postulated that chemical reactions resulted in the rearrangement of the reacting atoms.......

Answer 2

Answer:

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.
