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.
The symbol for iron chloride is FeCl3.
FeCl2 is an ionic compound. It is composed of iron (Fe) cation and chloride (Cl) anion, which are held together by ionic bonds formed through the transfer of electrons from Fe to Cl.
The cation Mn2S3 contains a manganese ion (Mn) with a charge of +2. Therefore, the ion symbol for this cation is written as Mn^2+.
Lithium bromide (LiBr) is a compound, not a cation. The cation is Li+.
The chemical formula (not symbol) of potassium bicarbonate is KHCO3.
FeCl2, FeCl3
The symbol for iron chloride is FeCl3.
The ferrous chloride is FeCl2.
FeCl2 is an ionic compound. It is composed of iron (Fe) cation and chloride (Cl) anion, which are held together by ionic bonds formed through the transfer of electrons from Fe to Cl.
The cation of chromium is Cr3+.
The cation Mn2S3 contains a manganese ion (Mn) with a charge of +2. Therefore, the ion symbol for this cation is written as Mn^2+.
Lithium bromide (LiBr) is a compound, not a cation. The cation is Li+.
The symbol of calcium is Ca.
The chemical formula (not symbol) of potassium bicarbonate is KHCO3.
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.
The symbol for the cation formed when a potassium atom loses one electron is K+, and is named the potassium ion.
The chemical symbol for iron is Fe, and the symbol for chlorine is Cl. If you meant when they are combined, there are two possibilities: FeCl2 for ferrous chloride or FeCl3 for ferric chloride.
