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

Objectives: to know that some metals are more reactive than others 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!!! P lease Potassium S top Sodium C alling Calcium M y Magnesium Z ebra Zinc I n Iron C lass, Copper S he Silver G runts! Gold To help us remember…

Objectives: to know that some metals are more reactive than others 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 Metals What about a real chemical reaction…? …Magnesium and Copper Sulphate Magnesium + Copper Sulphate Copper + Magnesium Sulphate

The Reactivity of Metals Objectives: to be able to work out the products of displacement reactions True or False? Silver reacts quickly with other substances FALSE

Sodium could displace copper from copper sulphate solution TRUE The Reactivity of Metals Objectives: to be able to work out the products of displacement reactions True or False?

Gold could displace silver from silver nitrate solution FALSE The Reactivity of Metals Objectives: to be able to work out the products of displacement reactions True or False?

The Reactivity of Metals Objectives: to be able to work out the products of displacement reactions zinc + iron sulphate  iron + zinc sulphate copper + sodium chloride  NO REACTION sodium + silver nitrate  silver + sodium nitrate

The Reactivity of Metals Finally… a VERY reactive metal!
