Giant ionic
Why do IONIC substances have high melting and boiling points?
Strong electrostatic attraction between IONS
Why do IONIC substance conduct electricity when melted or dissolved?
IONS can move
Why don’t IONIC substances conduct as solids?
IONS can’t move in solids
Why do MOLECULAR substances have low melting and boiling points?
Weak forces BETWEEN MOLECULES
Why don’t molecular substances conduct electricity?
No charged particles to move and carry the charge
What element are graphite and diamond made from?
Both carbon
Why can diamond be used as a cutting tool?
It’s very hard
Describe the structure of a diamond
Each carbon is covalently bonded to 4 other carbons
In a giant lattice
Describe the structure of graphite
Each carbon is joined to 3 others
To for layers of carbons
With delocalised electrons between them
