प्रश्न
State the reason to explain why covalent compounds "are bad conductors of electricity".
Give reason for the following:
Covalent compounds are bad conductors of electricity.
उत्तर
In covalent compounds, electrons are stuck in the links between atoms instead of being able to move around freely. These molecules can't carry electricity without free ions or electrons that aren't stuck in one place.
