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.
Ford 385-series engine. The Ford FE engine is a medium block V8 engine produced by the Ford Motor Company and used in vehicles sold in the North American market between 1958 and 1976. The FE, derived from 'Ford-Edsel', [1] was introduced just four years into the short-lived Ford Y-block engine, which American cars and trucks were outgrowing.
There are 28 known radioactive isotopes and 8 nuclear isomers, the most stable of which are 60 Fe (half-life 2.6 million years) and 55 Fe (half-life 2.7 years). Much of the past work on measuring the isotopic composition of iron has centered on determining 60 Fe variations due to processes accompanying nucleosynthesis (i.e., meteorite studies ...
The red lepidocrocite (γ-Fe(O)OH) occurs on the outside of rusticles, and the orange goethite (α-Fe(O)OH) occurs internally in rusticles. When Fe 2 O 3 ·H 2 O is heated, it loses its water of hydration. Further heating at 1670 K converts Fe 2 O 3 to black Fe 3 O 4 (Fe II Fe III 2 O 4), which is known as the mineral magnetite.
The alpha iron (α-Fe) is a body-centered cubic (BCC) and the gamma iron (γ-Fe) is a face-centered cubic (FCC). At atmospheric pressure, three allotropic forms of iron exist, depending on temperature: alpha iron (α-Fe, ferrite), gamma iron (γ-Fe, austenite), and delta iron (δ-Fe). At very high pressure, a fourth form exists, epsilon iron ...

Ferric. Potassium ferrioxalate contains the iron (III) complex [Fe (C2O4)3]3−. 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 (FeCl3). The adjective ferrous is used instead for iron (II) salts, containing the cation Fe 2+.
Fundamentals of Engineering exam. The Fundamentals of Engineering (FE) exam, also referred to as the Engineer in Training (EIT) exam, and formerly in some states as the Engineering Intern (EI) exam, is the first of two examinations that engineers must pass in order to be licensed as a Professional Engineer (PE) in the United States.
