The Reactivity of Metals
Today’s Objectives
By the end of this lesson, you will:
know that some metals are more reactive than others
understand what happens in displacement reactions
be able to work out the products of displacement reactions
The Reactivity of Metals
Objectives: to know that some metals are more reactive than others
Reactivity – a measure of how readily and violently a substance will react with another substance
Grrrunt!!!Please Potassium
Stop Sodium
Calling Calcium
My Magnesium
Zebra Zinc
In Iron
Class, Copper
She Silver
Grunts! Gold
To help us remember…
The Reactivity of Metals
Objectives: to understand what happens in displacement reactions
Displacement – when a more reactive metal takes the place of another one in a compound
Objectives: to understand what happens in displacement reactions
The Reactivity of Metals
Angelina is more reactive than Jennifer….
…so Angelina displaces Jennifer and wins Brad!
Objectives: to understand what happens in displacement reactions
The Reactivity of MetalsWhat about a real chemical reaction…?
…Magnesium and Copper Sulphate
Magnesium + CopperSulphate
Copper + Magnesium Sulphate
The Reactivity of Metals
