🧠 The Ellingham Hierarchy
In an Ellingham diagram, the metal that is "lower" on the graph is more oxygen-hungry. A metal can reduce the oxide of any metal that lies above it in the diagram because the net  for the reaction will be negative.

🗺️ The Method of Reduction
1. The Position: Magnesium's line for  formation lies below the line for  formation at temperatures below the crossover point.
2. The Principle: Metals with a more negative  of formation for their oxides act as reducing agents fo
