It has been worked, or See more Laboratory routes For a few limited purposes when it is needed, pure iron is produced in the laboratory in small quantities by reducing the pure oxide or hydroxide with hydrogen, or forming iron pentacarbonyl and heating it to 250 °C so that it … See more WebSome elements can form ions with two or more different charges. Iron (Fe), for example, can form both an iron ion with 2+ (Fe 2+) and an iron ion with 3+ (Fe 3+). Naming Ions. A neutral sodium (Na) atom loses one electron to form a sodium ion (Na +) with a charge of 1+ (see Table 2.8). A positive ion, or cation, has the same name as the element.
