Problem

Predict the relative reducing power of the group 2A elements. Rank from strongest to weakest reducing agent. To rank items as equivalent, overlap them.

Ca, Mg, Be, Sr, Ba

Solution

We are being asked to rank the given group 2A elements from strongest to weakest reducing agent. A reducing agent is the species that are being oxidized in a redox reaction. Recall the mnemonics LEO GER.

Lose               Gain

Electron         Electrons

Oxidation       Reduction

The strongest reducing agent would be the element that would be easily oxidized or easily loses an electron. The ease to remove an electron from an element is related to their atomic size.
