C2

1. Nano-Crystals

   • smaller crystals than the size of crystals in normal metals

2. nanotubes and graphite

   • Graphite can conduct electricity because the electrons can carry charge through the graphite
   • Carbon nanotubes are used as lubricants because the layers in nanotubes can slide

3. Alloys

   • Harder than normal metals because the atoms is alloys are different sizes

4. Diamond structures

   • Giant structure or lattice

5. Mass number and atomic numbers

   • Atomic number= number of protons
   • Mass number= number of protons+number of neutrons
