Which is greater fe2+ or fe3+ and why

Among the Iron (II) ion Fe 2 + (charge is 2+) and Iron (III) ion Fe 3 + (charge is 3+), the magnitude of positive charge is higher on Iron (III) ion Fe 3 +. Therefore, the size of Iron (III) ion Fe 3 + will be smaller than Iron (II) ion Fe 2 +. Why do Iron ions have two charges, +2 and +3? Iron ions have two charges, +2 and +3. This is because the electrons in an iron atom are at different energy levels. Once converted, Fe2+ serves to support various biological functions. Iron promotes the synthesis of oxygen transport proteins such as myoglobin and hemoglobin and the formation of heme enzymes and other iron-containing enzymes involved in electron transfer and redox reactions 1. Iron (II) ion will gain electrons as an oxidizing agent because it will be reduced as the other species gives up electrons to be oxidized. When iron (ll) is exposed to air, oxidation will occur and form iron (ll) salt, which gives a brown color. Oxidation refers to the loss of electrons, gain in oxygen, loss of hydrogen, or increase in the oxidation state. A ferrous ion is a divalent iron compound ion. It has a +2 oxidation state and is light green, while the ferric ion is trivalent and is very pale violet or brown. Fe2+ ions migrate from the anode region and react with water to form Fe3+ ions. Iron (as Fe2+, ferrous ion) is a necessary trace element all known living organisms use. Iron-containing enzymes, usually containing heme prosthetic groups, participate in the catalysis of biological oxidation reactions and the transport of some soluble gases.
