What is the chemical symbol for Iron?

The chemical symbol for Iron is Fe, which is derived from the Latin word "ferrum." In the periodic table of elements, each element is represented by a unique one- or two-letter symbol, and this system allows for a standardized method of identifying the elements. Iron is a transition metal and is known for its significant role in engineering and construction, as well as its essential function in biology, particularly in hemoglobin for transporting oxygen in the blood.

Other options represent different elements: Cu is the symbol for Copper, Ag is the symbol for Silver, and H is the symbol for Hydrogen. Each of these symbols corresponds to distinct elements with their unique properties and uses, but only Fe specifically denotes Iron.
