6.1: Oxidation and Reduction Review - Chemistry LibreTexts

WebAfter the electrons are gained, the reactant is considered reduced. The reactant being oxidized is providing electrons for the reduction reaction and is called the reducing agent. The reactant being reduced is accepting electrons from the oxidation reaction and is called the oxidizing agent. WebPhosphorus is therefore oxidized in this reaction, and oxygen is reduced. Calcium (EN = 1.00), on the other hand, is significantly less electronegative than phosphorus (EN = 2.19). When these elements react, the electrons are drawn toward the more electronegative phosphorus atoms. As a result, calcium is oxidized and phosphorus is reduced. shiny maxrequestsize
