Iron will form a cation. Depending on how many electrons it lose, it could be Fe2+ or Fe3+. There is more than one transition state.
Ferric sulfate contains trivalent iron cations and ferrous sulfate contains divalent iron cations. As a consequence of this, they have different ratios of iron to sulfur or oxygen and other different properties.
Iron atoms release their outermost electrons to form cations. They are Iron(II) and Iron(III) ions. In aqueous medium, Iron(II) is more stable.
From the second row of the periodic table alone, there are Li+1 and Be+2. All the remaining members of periodic columns 1 and 2 form corresponding cations. The most common polyatomic cation is NH4+1.

Cations are attracted to anions.
Iron loose electrons and form cations.

A transfer of electrons between two distinct chemical entities. One of the simplest examples is a single displacement, for example, elemental iron atoms transfer electrons to silver cations, changing the silver cations to elemental silver and the iron atoms to cations.
Iron is a metal, and is made of iron atoms. When it reacts to form a compound the iron atoms will lose electrons and become cations, either Fe2+ or Fe3+. All metals form cations when they form ionic compounds.

Drops of liquid metallic mercury will form and drop to the bottom of the solution: Iron is higher in the electromotive series than mercury and will therefore displace mercury from compounds of mercury, the iron being changed to cations that replace as many of the mercury cations in the solution as is stoichiometrically possible, based on the amount of iron added to the solution and the amount of mercuric nitrate originally present.
Iron reduce silver cations.
