Can you read through the work you did last

lesson?

Do now!

• Review the properties of metals

• Understand that elements can be arranged in order of their reactivity

• Relate the pattern of the elements and their compounds to a reactivity series

• Recall reactions used to establish the order of reactivity

This lesson

Properties of metals?

All metals are;

• Good conductors of heat and electricity

• Shiny

All metals are;

• Good conductors of heat and electricity• Shiny

Metals are often• Dense• Ductile• Malleable• Having high melting and boiling points• Sonorous

Reactivity Series

• YouTube - Rubidium and Cesium in water

• YouTube - Alkali metals in water ( Not the braniac version )

• YouTube - Brainiac Alkali Metals

• Alkali Metal Bangs

Could you quietly and sensibly gather your

stools around Mr Porter?

Reactivity Series

Reactivity Series

Can you carefully copy this down please?

Reactivity Series

• potassium• sodium• lithium• calcium• magnesium• aluminium• zinc• iron• tin• lead• copper• silver• gold

Can you compose a sentence to help you remember this order? (important)

Reactions to establish order

• with air

• with water

• with acid

Mr Porter will show you some

demonstrations and then he will give you

a sheet to stick in.

Displacement reactions

Displacement reactions

A more reactive metal will displace a less reactive metal

Displacement reactions - Thermite

2Al + Fe2O3 Al2O3 + 2Fe

YouTube - Thermite on Car

YouTube - Thermite Experiment

Let’s try some displacement reactions ourselves
