Giant Covalent Substances
1
Graphite
Each Carbon atom is joined to three others through covalent bonding
The atoms form layers which can slide over each other easily, as there are no covalent bonds between them and the atoms are the same size - no distortion.
This makes it very soft, perfect for use in pencils, as layers can move onto the paper.
As there are delocalised electrons, graphite can conduct electricity
Bonds between
layers are longer and
weaker than those
within the layers
Giant Covalent Structures
Giant Covalent Substances
Also known as macromolecules
Create a giant lattice
Non - Metal atoms
Large amount of bonds = strong structures
Large amount of bonds to broken = high melting points
Silica
Found in sand.
Similar structure to diamond, as it has a high melting point and is very strong.
SiO2
Diamond
Made up of Carbon atoms
Each atom joined to four others through covalent bonding
Does not conduct electricity, as there are no delocalised electrons to carry a charge
Has a very high melting point
Extremely hard
All bonds are the
same length
