Giant Covalent Structures Flashcards
1
Q
How are they different to giant ionic structures?
A
There are no charged ions
2
Q
How are all the atoms bonded to each other?
A
By strong covalent bonds
3
Q
There are lots of these bonds which means…
A
It takes a lot of energy to break them, so giant covalent structures don’t have very high melting and boiling points
4
Q
What do they not do?
A
They don’t conduct electricity - even when molten (except for graphite)
5
Q
What are they usually like in water?
A
Insoluble
6
