• When a non metal and a metal react, an ionic bonding takes place.
• Giant ionic lattices are formed when ions are held together by a strong electrostatic force of attraction.
• Ionic compounds have a high melting and boiling point due to the Strongs bonds and the high amount of heat energy to break the bonds away.
• When the ionic compound is liquid it can conduct electricity as the ions can move and carry electrical charge.
• When non metals react with teacher, covalent bonding takes place.
• Weak intermolecular forces are forces that are not strong enough to hold the molecules together.
• In a small covalent bond they have a low melting and boiling point as they have weak intermolecular forces which do not require a lot of energy to overcome.
• Graphite has high melting and boiling point as they have a strong covalent bond, they have delocalised electrons which carry an electric charge and transfer it through layers.
• Buckministerfullerene shaped as a hollow sphere, they can be used as catalysts.
• Metals are malleable as they have layers of ions which slide over each other.
• Metals conducts electricity as they have delocalised electrons that are free to move and carry an electric charge through them.
• As the particle size decreases, the surface area to volume ratio increases, it is inversely proportional.
• Simple molecules have low mpt and bpt because they have weak intermolecular forces between molecules.
• Simple molecules do not conduct electricity as they do not contain particles that are charged.
• Diamond contains 4 carbon atoms in a giant covalent structure.
• Graphite contains 3 strong covalent bonds with other Carbon atoms.
• Graphite is able to conduct electricity as each carbon atom has one delocalised  electron, which can move freely, and so is able to carry charge. 
• Fullerenes can form spheres around other molecules. Acts like a cage.
• Nanotubes are useful in electronics as they have one delocalised electrons which can carry charge.
• An alloy is a metal that has been combined with one of more elements
• Silvernanoparticles infused into masks and wound dressings to reduce the risk of infection.
