Giant Covalent Structures Flashcards
1
Q
Why can diamond not conduct electricity?
A
All the electrons in the structure of Diamond all electrons are fixed and held tightly within the covalent bonds, so they can’t move or flow
2
Q
How many bonds does each carbon atom have in diamond?
A
4 Very strong covalent bonds
3
Q
How many bonds does each carbon atom have in graphite?
A
3 covalent bonds, leaves 1 electron delocalised = conductive
4
Q
Which structure has weak and which has strong forces between layers?
A
Graphite = weak diamonds=no layers
5
Q
Why is graphite soft?
A
Layers of carbon can slide past each other
