Giant Molecules - The Structure of Diamond and Silicon.

For diamond, each
blue ball
represents a carbon atom.
The structure has billions of atoms and
extends in
all directions.
All
of the covalent
bonds in diamond are
identical.
It forms a giant
molecular structure.
A crystal of diamond is one
giant molecule!
The covalent
bonds are very strong.
Diamond is the hardest naturally occurring
material.
Silicon (used in microchips for computers)
has the same structure, with each
blue ball
being a silicon atom.
Silicon
dioxide (SiO2) is
sand (also called silica).
SiO2 has a similar structure and also
forms a giant molecule.
