A list of elements that organizes them in order of their reactivity is called

• Negativity Series

• Netflix Series

• Activity Series

• Displacement Series

Which one of the following would result in a displacement reaction?

• Iron with magnesium chloride

• magnesium with iron chloride

• Iron with Zinc Sulphate

• gold with silver nitrate

A displacement reaction will occur when...

• a more reactive metal displaces a less reactive metal from its compound.

• A less reactive metal displaces a more reactive metal from its compound

• Displacement only occurs when two of the same metals are reacted 

• Displacement reactions will only occur in metals above iron in the reactivity series
