=Revision: Reactivity of metals=

This is the list of the reactivity of metals with Potassium at the top as the most reactive and Platinum at the bottom as the least reactive metal.

To help you learn the learn the order, you can make up songs to help you remember. Here is one:


 * Please** - potassium - K
 * send** - Sodium - Na
 * charlies** - calcium - Ca
 * monkeys** - magnesium - Mg
 * and** - aluminum - Al
 * zebras** - zinc - Zn
 * in** - iron - Fe
 * lead** - lead - Pb
 * cages** - copper - Cu
 * securely** - silver - Ag
 * guarded** - gold - Au

This video below is about the reactions you get when you mix Alkali metals and water. media type="youtube" key="m55kgyApYrY" height="315" width="560"

Displacement reactions:
A displacement reaction is when a less reactive metal is kicked out by a more reactive metal. To explain this we will use the example of Brad Pitt, Jennifer Aniston and Angelina Jolie. Brad Pitt (Potassium, K) and Jennifer Aniston (Aluminium, Al) are happily partnered together but then Angelina Jolie ( Sodium, Na) comes along and because she is a more reactive metal Aniston is kicked out of the partnership and Jolie takes her place.
