Electron transfer takes place from a reducing agent which loses electrons to an density, solubility, polarity, texture and many others. 2. Reduction in Terms of Oxidation Number Reduction is decrease in the oxidation state or oxidation number of an atom in a reaction. Thus, oxidation is taking place and sodium is getting oxidized. WebElectronegativity is a chemical property that describes the power of an atom in a molecule to attract shared-pair electrons towards itself. You can see many examples of redox reactions also in your everyday life. We define oxidation as the loss of electrons by a chemical moiety. It is also the loss of oxygen from a substance. The oxidising agent, also known as the electron acceptor, is generally in one of its higher oxidation states since it will receive electrons and be reduced. Reduction in Terms of Electron Transfer Reduction is gain of electrons. A simple example is that of say sodium fluoride. The iron metal is oxidized to form the iron oxide known as rust.
