2. Relevant equations
3. The attempt at a solution
It has no free moving ions or electrons
Then, my teacher saw the electrons and gave 0 marks to the question(It was on the test paper)
He said that if he didn’t see electrons there, he would have given a mark.
Why? I don’t understand.
If it does not have free moving ions but have free moving electrons, then it will conduct. My answer should not be wrong!
