calcium chloride reaction to metal in egypt

The name of the salt formed by these ions must include the name of the metal AND its charge: iron(1+) chloride, iron(2+) chloride, iron(3+) chloride. Iron can also form covalent compounds. In this case there is no ion, no positive charge, but we can assign an informal charge based on its oxidation state (which is then referred to as its oxidation state or oxidation nuer).
