Answer:
reduced
Explanation:
To win the metallic product from the oxide, it demands that the metal be reduced.
During reduction a metal will:
- gain electrons.
- there would be removal of oxygen from the specie
- there would be decrease in oxidation number of the atom
- decrease in the number of electronegative atom surrounding the element.
The specie that is reduced will become the oxidant and reducing agent in the chemical reaction.
