Iron Phosphide
Fe - Iron P - Phosphorus
3 and 2 refer to how many atoms there are to make the compound neutral.
Phosphorus has a charge of -3 and Iron has a charge of +2.
*Note: Iron can have two charges, +3 and +2.
Iron with a positive charge of +3 is called Iron (III) or Fe (III)
Iron with a positive charge of +2 is called Iron (II) or Fe (II)
In this case it has a charge of +2. Also remember that Fe (III) and Fe (II) is represented by Roman Numerals NOT numbers.

Chemical formula for iron 2 phosphide?
The chemical formula is Fe3P2.
What is the formula for Iron II Phosphide?
Iron(II) Phosphide = Fe3P2 Iron(III) Phosphide = FeP
What is the chemical formula for ferric phosphide?
Fe3PO4
Which formula correctly represents the compound of iron oxide?
There are a umber of different oxides of iron. It depends of the oxidation state of iron. Hematite is Fe2O3, iron(III) oxide. Magnetite is Fe3O4 (diron(II) diron(III) oxide. There is also FeO, iron(II) oxide.
What is the formula of the compound iron III phosphide?
FeP. Iron(III) means that the iron has an oxidation state of 3, and could be considered to be Fe3+. Phosphides generally contain P3- and this is true for the group1 and group 2 metals There is one iron phosphide Fe3P used as a semiconductor, so it is not ionic! You cannot use oxidation number nomenclature on that compound you have to go the "triiron monophosphide" route instead. I do not think there is actually a compound with the formula FeP. Naming phosphides using the oxidation state nomenclature is risky, phosphorus forms many different "ions" and also forms binary compounds where the phosphorus is "interstitial" .
