Iron is a chemical element; it has the symbol Fe (from Latin ferrum 'iron') 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, forming much of Earth's outer and inner core.
The word ferrous is derived from the Latin word ferrum, meaning "iron". In ionic compounds (salts), such an atom may occur as a separate cation (positive ion) abbreviated as Fe 2+, although more precise descriptions include other ligands such as water and halides.
The Latin term, during the Roman Empire, was aes cyprium; aes was the generic term for copper alloys such as bronze. Cyprium means "Cyprus" or "which is from Cyprus", where so much of it was mined; it was simplified to cuprum and then eventually Anglicized as "copper" (Old English coper/copor). · Symbol Cu is from the Latin name cuprum ("copper").

118 chemical elements have been identified and named officially by IUPAC.A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z).
Iron, for which ferrum is the Latin term and the source of its chemical symbol Fe. Ferrum, Virginia; Ferrum College, in Ferrum, Virginia; Ferrum 49, Polish locomotive class; Ferrum SA, a Polish steel pipe producer established in 1874.
In chemistry, iron(III) or ferric refers to the element iron in its +3 oxidation state. Ferric chloride is an alternative name for iron(III) chloride (FeCl 3). The adjective ferrous is used instead for iron(II) salts, containing the cation Fe 2+. The word ferric is derived from the Latin word ferrum, meaning "iron".
Latin antimonium, the origin of which is uncertain: folk etymologies suggest it is derived from Greek antí ('against') + mónos ('alone'), or Old French anti-moine, 'Monk's bane', but it could plausibly be from or related to Arabic ʾiṯmid, 'antimony', reformatted as a Latin word.
