C2
Ionic bonding
Electrostatic attraction between positive and negative ions, relatively strong
Ionic compounds are held together in a giant ionic lattice which means there are strong electrostatic forces in all directions
High melting and boiling points as there are strong electrostatic forces between oppositely charged ions
Do not conduct electricity when solid as the ions are held in place, conducts when melted as the ions are free to move

Metals as conductors
Good conductors of electricity because of delocalised electrons in the metals can pass charge through and thermal energy
