• Salt
Here are some of the words we will be using this lesson…
1) Create sentences which use the keywords correctly.
2) Put your hand up if there is any key word from the list that you don’t know the meaning of.
Match the following
Metals This is formed when a metal reacts with oxygen.
Metal oxideMost of these are shiny and good conductors of electricity and heat.
Metal hydroxideThis is a colourless gas found in all acids.
HydrogenThis is a compound consisting of a metal plus oxygen and hydrogen.
A saltThis is a metal compound formed when a metal reacts with an acid.
Reactivity seriesThis is an arrangement of metals in the order of how vigorously they react with oxygen, water and dilute acid.
Think about it in silence!!!

Reactivity series (Task 1)
• Using evidence from your work, arrange above metals into an order of reactivity with the most reactive metal at the top and least reactive metal at the bottom.
• Evidences are the results recorded in your book (Reaction of metals with Oxygen, acids and water)
copper, gold, magnesium, potassium, iron, calcium, silver, zinc, sodium.
Extension: Make a pneumonic for your reactivity series.

The Reactivity of Metals
What will happen if you put these two together……Magnesium and Copper Sulphate ?

What about a real chemical reaction…?…Magnesium and Copper Sulphate
Magnesium + CopperSulphate
Copper + Magnesium Sulphate
The Reactivity of Metals
Angelina is more reactive than Jennifer….
…so Angelina displaces Jennifer and wins Brad!
If the metal is more reactive than the metal in the compound, it competes with the less reactive metal.
+less reactive

When does displacement happen?
+ more reactive metal

less reactive metal
If the metal is less reactive than the metal in the compound, it will not compete and so there is no reaction.

• You are going to perform a series of reactions to see the reactivity series in action.
• You will be testing the relative reactivity of magnesium, zinc, iron, and copper.
Investigating reactivity
Copy the Table into your book
magnesium sulfate zinc sulfate iron sulfate
copper sulfate
magnesiumzincironcopper
Method:• Collect the metals and solutions and 3 test tubes
and a test tube rack• Measure 10mL of each sulfate you need to test
into the test tubes• Carefully place the metal into the test tube• Repeat with each metal• Record if there was a reaction in your table• Complete the word equations of the reactions
that occurred
Investigating reactivity

Review
• Swap books with the person next to you and look over their work. Write a WWW and EBI statement.
• Stand up if you have developed some skills this lesson? What are they?
• Tell the person next to you three things you have learnt this lesson.
• Did you successfully complete tasks at your target level?• If not, what do you need to do next in order to meet your
target level? Record this in your diary to be done as part of your extended learning at home.
• Is there any part of the lesson you think you need to go over again next lesson?
• How will you remember what you have learned today for your exam?
