Card preview (19)
what shape molecule is C₆₀ Fullerene
sphere ( football shape)
C₆₀Fullerene is made of what atoms
carbon
how many carbon atoms are joined together in C₆₀Fullerene
60
what structure does C₆₀Fullerene have
simple molecular structure
can C₆₀Fullerene conduct electricity
NO
C₆₀Fullerene has low melting points because
There are weak intermolecular forces and little energy is needed to overcome these forces
diamond is what structure
GIANT covalent
each carbon in diamond is bonded to how many other carbon atoms
4
are there free electrons in diamond and why
NO because there are 4 bonds of carbon to each carbon
properties of diamond (3)
• high melting point • DOES NOT conduct electricity • Is hard and dense
what is diamond used for (2)
jewellery and cutting
each carbon atom in graphite is bonded to how many other carbon atoms
3
Graphite has a _______ structure
GIANT covalent
what structure does graphite have
its in layers
does graphite conduct electricity
yes
why does graphite conduct electricity
because there is a delocalised electron that exists between the layers due to there only being 3 bonds for each carbon atom the unpaired electron becomes delocalised
graphite has ____ forces
weak intermolecular forces of attraction
properties of graphite (3)
• conducts electricity • high melting and boiling point • soft and slippery ( layers can be moved)
In C₆₀Fullerene, each carbon atom is bonded to how many others
