C Two

Question 1

What type of bonding is ionic?

Answer 1

metal + non metal

electrons transferred

Question 2

What type of bonding is covalent?

Answer 2

Non metal + non metal

sharing of electrons

Question 3

What type of bonding is metallic?

Answer 3

metal + metal

positive ions and delocalised electrons

Question 4

What is a metal?

Answer 4

positive ions and delocalised electrons that are free to move which conduct electricity and heat, layers slide across each other which makes the metal soft

Question 5

What is an alloy?

Answer 5

positive ions and delocalised electrons + something else (metal and non metal) distorted layers can’t slide which makes it hard

Question 6

What is ionic bonding?

Answer 6

giant ionic lattice which have high melting and boiling points which conduct electricity when molten or dissolved as ions must be free to move

Question 7

What is simple covalent bonding?

Answer 7

EG. o2 co2 h2o h2
low melting/boiling points
gas/liquid at room temp
don’t conduct electricity

Question 8

What is giant covalent bonding?

Answer 8

graphite, diamond, silican dioxide, carbon nanotube, buckminlerfullercone 
giant covalent structure
high melting/boiling points
don't conduct electricity
don't dissolve

Question 9

What is a diamonds structure?

Answer 9

giant covalent lattice
made up of carbon each make 4 bonds
hard

Question 10

What is graphites structure?

Answer 10

giant covalent compound
pure carbon
3 bonds to other carbons
soft
conducts electricity
in sheets
space electron in sheets
graphite is a single sheet

Question 11

Carbon Nano tubes?

Answer 11

made of carbon
3 bonds
hard
used for drug delivary

Question 12

Buckminsterfllerene?

Answer 12

lubricant

reinforcement

Question 13

polymers in chains?

Answer 13

cross links
fixed in place
slide across each other

Question 14

polymers with no chains/cross links?

Answer 14

can’t slide across each other

melt
