Because it is in the transition series :)
actually it is in the transition metals* in the Periodic Table of elements.
and an improved answer is that it holds only one type of atom.
No. It is not. Iron is an element. Oxygen is an element. Iron Oxide is a compound.
in its pure form, iron is an element, but that may not be what you are referring to.... if you have iron oxide (rust), this is a compound of iron and oxygen.
No, iron oxide is not an element. It is a compound of iron and oxygen. (There is more than one kind of iron oxide, too.)
No, iron chloride is not an element. Iron chloride is a chemical compound composed of the elements iron and chlorine. Iron is the element with the atomic number 26 and symbol Fe, while chlorine is the element with the atomic number 17 and symbol Cl.
Iron is a natural element that is found in the Earth's crust and is not synthesized.
Pure Iron is an element with the symbol Fe.Pure iron is an element, but what is called "iron" in ordinary speech often contains some impurities and if so is a mixture.Iron is an element
Iron is an element, and there is only one element called iron (Fe). There are no iron element(s), but if you mean isotopes, then some iron isotopes are stable, and some aren't. No known element is stable in of it's isotopes.

Sand is NOT an element. Iron IS an element.
Anything that appears on the periodic table is a pure substance called an element. Uranium appears on the periodic table with the atomic number 92, it is therefore an element.
Iron belongs to the mineral group called "native elements."
Iron is a element, it isn't a compound
iron (i.e., pure) is a metal / element in the periodic table, but types of iron are compounds like wrought iron, pig iron cast iron., etc.
No. It is not. Iron is an element. Oxygen is an element. Iron Oxide is a compound.
Iron is an element. It is a pure substance that consists of only one type of atom, specifically iron atoms.
Iron (Fe) is an element
