key definition 

The higher a metal is on the reactivity series, the more reactive it is. This is as it will be more likely to form a positive ion.

you need to know this 

stick a copy of this in your book 

what do we think a displacement is ?

A displacement reaction is where a more reactive substance takes the place of a less reactive substance.

what kind of displacement reaction is happening here ?

which elements are not more reactive then copper ?

1. gold
2. hydrogen
3. tin
4. pottasium

w hich reaction would occur ?

1. ironsulfate + copper
2. copperbromide + gold
3. magensium + iron oxide
4. calcium nitride + aluminium

what needs to be the case of a displament reaction to occur ?

1. metal on its own is more reactive
2. the metal salt is more reactive
3. the metal on it own is less reactive
4. only when the metal is in group 1
