Atomic Structure

Giant Molecules - The Structure of Diamond and Silicon.

Diamond Giant Molecule
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.
