Explanation:
free electron - electron that is not attached to an atom or ion or molecule but is free to move under the influence of an electric field.
Free electrons are actually those electrons which are able to move freely without much resistance to their movements.
In case of metal every valence shell electron is a free electron and is not offered much resistance by the strong nuclear attraction force by the nucleus.
In case of a non metal as the outer valence shell electrons are not loosely held they hardly have free electrons.
The term free electron is actually a mind concept that the more easily an electron can move in its surroundings the more free it is said to be.
However you can't say all the valence electron are actually free in metal....
Sometimes some electrons are free at the same time other valence electron may not be free.
Overall it is the property of a substance to have more or less free electrons.
However someone gets confused free electrons as isolated electrons as the beam of electrons but that is not actually correct.
More detailed answer will be quite confusing so dear just stick to syllabus and don't try to study irrelevant things.
