Curie Notes 12: Oxidation and Reduction, Electrons Changing Hands
Zinc turns copper sulfate pale, iron rusts, and in 1910 I made radium a metal. All three are electrons passing from one atom to another.
Learn oxidation and reduction, oxidation-number rules, oxidising and reducing agents, half-reactions, balancing redox in acid, the activity series and rust.
