Fe3+ is smaller. Its ionic radius is 63 pm, while Fe2+ has an ionic radius of 77 pm. (For comparison, the Fe atom has a radius of 140 pm.) This is because the outermost electron in the 2+ ion is pulled off to form the 3+ ion. This outermost electron was the most weakly held. The remaining electrons are closer to the nucleus.
A. Fe^2+ ==> Fe^3+ + e- is an oxidation reactionB. Fe^3+ +e- ==> Fe^2+ is a reduction reactionC. Fe(s) ==> Fe(l) is neither an oxidation nor a reduction reaction. It is a phase change.D. Fe + 2e- ==> Fe^2+ is not a possible reaction.
The name of the ionic compound Fe2+ is iron(II) or ferrous ion.
The ferrous (Fe2+) state is typically more soluble than the ferric (Fe3+) state because Fe2+ ions form more stable complexes with ligands in solution. This increased solubility can make ferrous compounds more bioavailable for biological processes and nutrient uptake.

Iron is a metal that can form three ions: Fe2+, Fe3+, Fe4+.

The name of the ionic compound Fe2+ is iron(II) or ferrous ion.
Potassium thiocyanate can be used to confirm the oxidation of Fe2+ ions to Fe3+ ions by forming a blood-red complex with Fe3+, known as iron(III) thiocyanate. Upon the addition of potassium thiocyanate, if a blood-red color formation is observed, it indicates the presence of Fe3+ ions, confirming the oxidation of Fe2+ ions.

Fe2+ and Fe3+.
Iron has 2 oxidation states: Fe2+ and Fe3+ .
ferrous ions and Fe3+ is ferric ion
The formula for ferric ion is Fe3+. It is the ion form of iron when it has lost three electrons.
