Question 1

Allotrope

Answer 1

Different structural arrangements of the same type of atom.

Question 2

Different allotropes of C

Answer 2

Fullerenes: Allotrope of C where the atoms are arranged in a series of pentagons and hexagons. (E.g Buckyball)

Graphene: “single layers of graphite”
- conductive like graphite but extremely strong and tuff

Nanotubes:
- Long, hollow structure with walls formed from graphene
- Conductive but strong
- Diameter of the cylinder: 1 nanometre (10^-9 metres)

Question 3

Nano materials

Answer 3

Substances (natural or synthetic) that are composed of single units that exist in the nanoscale.
- Substances that contain particles in the size range 1-100nm and have specific properties relating to the sie of these particles which may differ from those of the bulk material
