#1
Front (Question)

giant covalent structures

Back (Answer)

non-metals form giant structures with atoms joined by covalent bond.

#2
Front (Question)

Diamond

Back (Answer)

1) has four strong covalent bond 2) has a high melting and boiling point because of its strong covalent bond. 3) does not conduct electricity because there is no free moving electron to carry a electric charge.

#3
Front (Question)

the properties of graphite

Back (Answer)

1) has a high melting and boiling point 2) is soft and slippery 3) great conductor of electricity and heat

#4
Front (Question)

what type of structure is graphite

Back (Answer)

hexagonal rings

#5
Front (Question)

why is graphite slippery

Back (Answer)

the hexagonal rings are in layers. there are no covalent bond between the layers so they slide

#6
Front (Question)

why can graphite conduct electricity

Back (Answer)

delocalised electrons can move. this means they can conduct thermal energy and electricity.

#7
Front (Question)

graphene properties

Back (Answer)

1) one atom thick 2) good conductor of electricity because of delocalised electrons 3) it has a strong covalent bond

#8
Front (Question)

fullerenes properties

Back (Answer)

1) molecules with carbon atom with hollow shape 2) fullerene can be use for pharmaceutical delivery, catalyst and lubricants.

#9
Front (Question)

carbon nanotubes properties

Back (Answer)

1) has high tensile strength 2) excellent conductors of heat and electricity
