Reactivity Series of Metals (1)

Vigour of the reactions of reactive metals

In a vigorous reaction between a more reactive metal such as magnesium and oxygen, a bright flame is observed

Vigour of the reactions of less reactive metals

In a less vigorous reaction between a less reactive metal such as iron and oxygen, only a glow or slow change in colour is observed

Reactivity of metals (1)

Different metals have different reactivities towards oxygen

Reactivity of metals (2)

Metals that are more reactive towards oxygen react more vigorously with oxygen

Reactivity series of metals

Is a list of metals arranged in order of their reactivity towards oxygen

The most reactive metal in the metal reactivity series

Potassium (K)

The least reactive metal in the metal reactivity series

Gold (Au)

The position of a metal in the reactivity series of metals

Depends on the reactivity of the metal when reacting with oxygen

Safety measures when using glass wool fibres

- Use forceps to handle them - Make sure you wear safety glasses and cover your mouth and nose when handling glass wool
