Is Fe a molecule?
Fe (iron) is an element that is represented with no subscript, so it is an atomic element. PCl3 is made up of two nonmetals, so it is a molecular compound. LiBr is made up of lithium, a metal, and bromine, a nonmetal, so it is an ionic compound.
What is iron 1 iron 2 and iron 3?
Ferrous oxide, commonly known as iron(II) oxide contains iron that lost 2 electrons in the oxidation process. So it is able to bond with other atoms that have an extra 2 electrons. Ferric oxide, is commonly known as iron(III) oxide. It contains iron that lost 3 electrons.
What is iron compound?
Three oxygen compounds of iron are known: ferrous oxide, FeO; ferric oxide, Fe2O3; and ferrosoferric oxide, or ferroferric oxide, Fe3O4, which contains iron in both +2 and +3 oxidation states. Ferrous oxide is a greenish to black powder used primarily as a pigment for glasses.
What is the chemical name of FEP?
Iron phosphide is a chemical compound of iron and phosphorus, with a formula of FeP. … Iron phosphide reacts with moisture and acids producing phosphine (PH 3 ), a toxic and pyrophoric gas. Iron phosphide can be used as a semiconductor. It has use in high power, high frequency applications, such as laser diodes.
