Bonding and Structures (separate chem)

Giant lattice structure held together by attraction between  positive and negatively charged ions 

• simple covalent molecules
• metallic
• ionic
• giant covalent 

Sand, diamond and graphite

• simple covalent molecules

• metallic

• ionic

• giant covalent

Low melting and boiling points which increase with increasing molecule size due to increased intermolecular forces.

• simple covalent molecules
• metallic
• ionic
• giant covalent 

Melting points are very high – a large amount of energy is needed to break all the covalent bonds

• simple covalent molecules
• metallic
• ionic
• giant covalent 

Lattice structure in which all atoms are joined to others by covalent bonds

• simple covalent molecules
• metallic
• ionic
• giant covalent 

Conductors due to delocalised electrons

• simple covalent molecules
• metallic
• ionic
• giant covalent 

Melting points are generally high – lots of energy is needed to overcome the attractions between positive ions and delocalised electrons.
