A mnemonic to memorize the reactivity series

Our teacher gave this to us to memorize the reactivity series, essential to know the outcomes of many chemical reactions and also useful in electrolysis.

Here it goes:

"Please Charles Send Monkeys And Zebras In Lead Hard Cage with Maximum Security Guard."

See the first letter of each word in the sentence. Now here is the actual series, starting from the most active.

1. Potassium - K
2. Calcium - Ca
3. Sodium - Na
4. Magnesium - Mg
5. Aluminium - Al
6. Zinc - Zn
7. Iron - Fe
8. Lead - Pb
9. Hydrogen - H
10. Copper - Cu
11. Mercury - Hg
12. Silver - Ag
13. Gold - Au

NOTE: This series does not include all elements. But it helps to remember the position of the most common elements used in reactions.
Hope it helps!
