The symbol of the cation of FeCl2 is Fe2+. A cation is a positively charged ion and to find the formula of any compound you must balance the cations with the anions.
Fe^(2+) its name is the iron cation in oxidation state '2' . When combined, with say a sulphate anion it would be named as 'Ferrous sulphate'. NB Ferric sulphate is iron cation in oxidation state '3'. ( Fe2(SO4)3 ). Note the difference in spelling for different oxidation states.
Iron(III)nitride
The chemical name for Fe(NO3)2 is iron(II) nitrate.
iron(II) bromide, ferrous bromide, iron dibromide
Iron(II) indicates that the cation is Fe2+. The (II) indicates the oxidation number of iron in this case it has lost 2 electrons. ( OILRIG -oxidation is loss (of electrons), reduction is gain).
The symbol of the cation of FeCl2 is Fe2+. A cation is a positively charged ion and to find the formula of any compound you must balance the cations with the anions.
When a cation has more than one possible ionic charge you use either just the number (i.e. 2+) if it is in ion form or a roman numeral (II) in a name.

It is the iron(II) cation. The Fe atom loses two electrons to become doubly positively charged Fe2+ cation. Some of the compounds it might form are FeSO4 and FeCl2.
These formulas are: for iron (II), FeO, FeS, and FeCl2; and for iron (III), Fe2O3, Fe2S3, and FeCl3.
Pt(2+) is a cation of Pt(II).
The name of the compound iron II and oxygen (FeO) is iron(II) oxide - the correct name after the inorganic chemistry nomenclature of IUPAC - or ferrous oxide.
Iron(III)nitride
The chemical name for Fe(NO3)2 is iron(II) nitrate.
The chemical formula for iron(II) sulfate is FeSO4. It consists of the iron cation Fe2+ and the sulfate ion SO42
iron(II) bromide, ferrous bromide, iron dibromide
