Which of the following does not show electrical conduction
Options

Correct Answer:

Potassium and sodium are metals so have mobile electrons. In graphite, each of the C-atom is covalently bonded to three other C-atoms so one valence electron is available for electrical and thermal conduction there is no mobile electron present in diamond as each C-atom is bonded to four other C-atoms by covalent bond.
