Direct link to yuki's post There is not always a tra, Posted 7 years ago. So sodium is being Sodium and fluorine bonding ionically to form sodium fluoride.Sodium loses its outer electron to give it a stable electron configuration, and this electron enters the fluorine atom exothermically.The oppositely charged ions are then attracted to each other. 1 - A; 2 - B So, oxidising agents become reduced during chemical reactions. In this reaction, oxygen is added to iron, thus, iron is oxidized. oxidation state to distinguish it from everything else 1: kinetic energy; 2: potential energy, Select the arrow(s) that represent the direction(s) in which: oxygen, Core Written Exam - Esthetics - Paul Mitchell. to assign oxidation states. original redox reaction, because those two electrons So 7 minus 7 gives us an 3O2+4Fe 2Fe2O3 Use the symbol e for an electron.
