1.55C: Understand Why Covalent Compounds Do Not Conduct Electricity



COVALENT COMPOUND: Compound with bonds between Non-Metal and Non-Metal formed by shared pair of electrons between the two atoms

ELECTRICAL CONDUCTIVITY OF COVALENT COMPOUNDS:
s
  • Covalent compounds do not conduct electricity as all valence electrons are used in forming covalent bonds, therefore there are no delocalised electrons that are free to move to conduct an electric charge
s
Example: Water ( H2O )

Water does not conduct electricity as all valence electrons are used in forming covalent bonds, so there are no delocalised electrons that are free to move to conduct an electric charge
