1. A more reactive metal will displace a less reactive metal from a compound.
DB – p. 24
aluminum + iron(III) oxide →
iron + aluminum oxide
Because aluminum is more reactive than iron, it displaces iron from iron(III) oxide

2. nonmetals
metals

3. More reactive down larger atomic radius

4. Increases up a group

5. Observations: gas and heat produced
Na + H2O 
Na2O + H2
Observations: gas and heat produced

6. P. 108 (melting points) and p
P.108 (melting points) and p (bonding of period 3 and oxides) we will revisit in Topic 4
More to do with bonding/intermolecular forces
