Answer 1

The statement which is not a postulate of the atomic-molecular theory is: Under certain conditions, it is possible to change one element into another.

Procedure

The atomic-molecular theory has the following postulates:

the elements are comprised of identical atoms.

• all atoms of a single element have the same characteristic mass.

,

• the number and masses of these atoms do not change during a chemical transformation.

,

• compounds consist of identical molecules formed of atoms combined in simple whole-number ratios.
