1. What are three characteristics that ionic compounds have (when in a giant ionic structure)?
- high boiling point, always conducts electricity and cannot dissolve in water
- dissolve in water, low boiling point, can not conduct electricity
- conduct electricity when molten or dissolved, have high boiling points, dissolve in water
- always conducts electricity, low boiling point, cannot dissolve in water

2. How do the delocalised electrons in metallic bonding effect the melting point?
- They make the melting point lower because it stops the positive ions being attracted togther
- The more electrons there are, the stronger the bonding will be and the higher the meling point because the positive metal ions will have more electrons to be attracted to
- Because the shared pair of electrons create a strong intermolecular force
- They make the bonding between atoms weaker
3. What is the equation for the second ionisation of oxygen?
- O+ (g) -> O2+ (g) + e-
- O+ (l) -> O2+ (g) + e- (s)
- O2+ (g) -> O3+ (g) + e-
- O2- (g) -> O2+ (g) + H2O

5. What is ionic bonding?
