metallic

• often good conductors
• 'sea' of delocalised electrons is able to move and carry a flow of charge
• malleable as the layers of positive ions are able to slide over one another
• delocalised electrons prevent fragmentation as they can move around the lattice
• the electrostatic forces of attraction between the positive ions and delocalised electrons are very strong and require a lot of energy to overcome
• metallic substances have high melting points and are nearly always solid at room temperature
• mercury is the only liquid metal at room temperature
