Bonding properties

Elements such as diamond and graphite are examples of...

• simple covalent molecules

• metallic

• ionic

• giant covalent

Low melting and boiling points that rarely conduct electricity.

• simple covalent molecules

• metallic

• ionic

• giant covalent

Melting points are very high and they rarely conduct electricity as solid or liquid.

• simple covalent molecules

• metallic

• ionic

• giant covalent

Excellent conductors as solid and liquid due to a sea of delocalised electrons.

• simple covalent molecules

• metallic

• ionic

• giant covalent

Giant structures with high melting and boiling points but only conduct electricity when molten or dissolved in a solution.
