Y9 Chemistry - Fullerenes

Fullerenes(molecules of … arranged in … shapes like …)

molecules of carbon arranged in hollow shapes like spheres, tubes or cages

Structure of fullerenes (each carbon forms …, leaving … and creating … that curve into …)

each carbon forms three covalent bonds, leaving one delocalised electron and creating hexagons/pentagons that curve into a ball or tube

Properties of fullerenes (con… … because … can move, … due to many .,., high… because of hollow shape, low .,, because they are … not giant structures)

conduct electricity because delocalised electrons can move, strong due to many covalent bonds, high surface area because of hollow shape, low density because they are molecular not giant structures

Example of fullerenes (carbon … used for reinforcing … or delivering … in medicine)

carbon nanotubes used for reinforcing materials or delivering drugs in medicin
