Iron - Wikipedia

Iron ( / ˈaɪərn /) is a chemical element with symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, right in front of oxygen (32.1% and 30.1%, respectively), forming much of Earth's outer and inner core.

Formula for iron ore? - konodustrialmill

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe3O4) and hematite (Fe2O3). What is the symbol of iron ore? The Latin name for iron is ferrum, which is the source of its atomic symbol, Fe.
