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.
