1
Q
what is covalent bonding?
A
non metals sharing valance electrons to become stable
2
Q
what is the structure?
A
large continuous lattice
3
Q
examples?
A
- diamond
- sand
4
Q
What are their properties?
A
- hard
- very high melting point
- poor conductors
- brittle
5
Q
why are they hard?
A
due to huge lattice and very strong covalent bonds
6
Q
why do they have a very high melting point
A
due to huge lattice and very strong covalent bonds
7
Q
why are they poor conductors?
A
the electrons are localised
