Iron is a metal in group VIII of the periodic table with atomic number 26, an atomic weight of 55.85, and a density of 7.86. It has a melting point of 1539 C.

One biogeochemical cycle that is often overlooked, however, is Earth's iron (Fe) cycle (Figure 1). Numerous iron-containing minerals exist on Earth (Table 1 & Figure 2). These minerals are ...

Over the next billion years, Earth's ocean transformed from an iron-rich, anoxic sea to today's oxygenated body of water, according to the researchers. This also oxidized Fe(II) into Fe(III ...

The novel iron-based catalyst exhibits superior performance for ammonia (NH3) synthesis compared to a well-established, century-old counterpart, as reported by researchers at Science Tokyo. By ...

It uses chemical symbols from the periodic table to represent the elements involved. Iron is Fe and oxygen is O. When it’s in the air, oxygen is two atoms joined together, so it’s represented ...
