Answer:
This theory has some assumptions; they are: The valence electrons of metallic atoms are free to move in the spaces between ions from one place to another place within the metallic specimen similar to gaseous molecules so that these electrons are called free electron gas.

Free electron gas theory assumes (c) Electrons are free to move anywhere
- In free electron gas theory-free electrons are treated as gas molecules
- Also all the laws of the classical kinetic theory of gases can be applied to them
- Although the free electrons gas theory explains a lot of things, it fails to explain the electric specific heat and specific heat capacity of metals.
