Which sequence indicates correctly the increasing reactivity of metals?
(a) iron, zinc, magnesium, sodium, potassium
(b) sodium, potassium, magnesium, zinc, iron

Solution

(a) iron, zinc, magnesium, sodium, potassium

The reactivity of the metals decreases down the reactivity series. In the reactivity series, the given metals are arranged as: (more reactive) potassium, sodium, magnesium, zinc, iron (less reactive). Thus, option (a) correctly indicates the increasing reactivity of the metals.
