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.
The group of metals called the big three consists of iron, copper, and aluminum. These three metals are known for have good thermal and electrical conductivities.
Iron loose electrons and form cations.
Iron nitrate is a salt, not an acid. It is composed of iron cations and nitrate anions.
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 can exist as both cations and anions, depending on its oxidation state. In its common oxidation states, iron can form cations (Fe^2+ and Fe^3+) by losing electrons, or anions (Fe^2- and Fe^3-) by gaining electrons.

FeCO stands for Iron(II) Carbonate. It is a chemical compound composed of iron(II) cations and carbonate anions, with a chemical formula FeCO3.
Iron is in the 8th group on the periodic table and is categorized as a transition metal
Iron belongs to the transition state elements.
Iron is in Group 8 (VIII) of the periodic table, which is also known as the Iron Group or the Transition Metals Group. Iron is specifically located in Period 4.
An example of cations bonded together by mobile electrons is metallic bonding. In metallic bonding, metal cations are surrounded by a "sea" of delocalized electrons that move freely throughout the structure, holding the cations together in a lattice. This is commonly seen in metals such as copper, iron, and aluminum.
