Question

Name two metals above hydrogen and two metals below hydrogen in reactivity series

Answer 1

Answer:

Two metals above Hydrogen : Sodium (Na) and Potassium (K)

Two metals below Hydrogen : Copper (Cu) and Mercury (Hg)

Explanation:

The metal reactivity series shows how the reactivity of different metals decrease as we move down the series. Hydrogen lies about in the middle of the series.

Alkali metals and alkali earth metals like Sodium, Potassium, Magnesium and Calcium are highly reactive and are thus placed above Hydrogen in the series. Some other metals like Iron, Zinc and Aluminium are also more reactive than Hydrogen and are placed above it.

Noble metals like Copper, Silver, Gold, Mercury etc are less reactive than Hydrogen and are placed below it.
