What is needed for a substance to conduct electricity
A charged particle that can carry a charge though the structure and is free to move
Bond between a metal and non metal
Ionic
What occurs for an ionic bonds to form
Metal loses one or more electron
Non metal gains one or more electron
What forms when electrons are lost or gained
Ions
Why can’t ionic compounds conduct electricity when solid
Ions are in a fixed lattice position
When can Ionic compounds conduct electricity
When molten or in aqueous solution
Why can Ionic compounds conduct electricity when molten or in aqueous solution
Because ions are free to move and carry a charge
What is metallic bonding
Positive meal ions in a sea of negative delocalised electrons
Why is a metalic bond strong
Strong electrostatic forces of attraction between positive metal ions and a sea of negative delocalised electrons
Why can metals conduct electricity
They have a sea of delocalised electrons that are free to move thoiugh the structure and can carry a charge
Bonding that occurs between non metals
Covalent
Why do simple covalent molecules not conduct electricity
No delocalised electrons or charged particles
What covalent molecules can conduct electricity
Graphite
Graphene
Fullerenes
Why is graphite a good conductor
One delocalised electron to each carbon atom
