Metals that are higher in the activity series are more reactive than metals that are lower in the activity series.
<h3>Reactivity of metals</h3>
The reactivity of metals is determined by the position of the metals in the activity series of metals. Metals that are more reactive are found at the top of the series while metals that are less reactive are found at the bottom of the series.
In each case, the more reactive metal is as follows;
- Iron is more reactive
- Hydrogen is more reactive
- Zinc is more reactive
- Magnesium is more reactive
- Zinc is more reactive
- Iron is more reactive
