Question 1

how man carbon bonds do diamonds have
m/b

Answer 1

4 covalent bonds to 1 carbon atom
high melting and boiling points and strong millions covalent bonds

Question 2

what cant diamonds do

Answer 2

conduct electricty

Question 3

graphite: high..

Answer 3

high melting and boiling point

Question 4

graphite so- and sli-

Answer 4

soft and slippery

Question 5

graphite: good conductor of el- and he-e

Answer 5

elec and heat

Question 6

what is graphites structure

Answer 6

3 bonds
hexagonal rings in layers with no bonds inbetween layers allowing it to be slippery

Question 7

graphite: electron

Answer 7

each carbon atom has a single electron not in a covalent bond called delocalised electrons so they can move and conduct

Question 8

graphene: structure

Answer 8

single layer of graphite, one atome thick

Question 9

graphene: strength and conducting

Answer 9

extremely strong and conducts electricty due to delocalised electrons

Question 10

fullerenes: structure

Answer 10

hollow shapes, hexagonal rings, can have rings with 5 or 7 atoms
