The subscript of the second ion identifies the oxidation state of the transition metal
Determine the charge of the anion, then work backwards to find the charge of the transition metal cation needed to give a net charge of zero for the formula unit
A pure metal has the oxidation state zero.
There really isn't an exact chemical formula. Oxidation simply means the loss of an electron!
The chemical formula for calcium chloride is CaCl2. A formula is determined by chemical analysis.
The chemical formula of cupric oxide is CuO.
The oxidation of magnesium is a process, and as such has a chemical equation rather than a formula: 2 Mg + O2 -> 2 MgO. MgO is the chemical formula for the oxide of magnesium.

CaCl2. I determined it by knowing the common oxidation states for calcium and chlorine.
Oxidation
The chemical formula for calcium chloride is CaCl2. A formula is determined by chemical analysis.
Formula: BrN Br in 3+ oxidation state
With the 2 oxidation state. NiCO3
It indicates the oxidation state.
For the one oxidation state. HgNO3 for the two oxidation state. Hg(NO3)2
Calcium's chemical symbol is Ca. Calcium's oxidation number is +2.Chloride's chemical symbol is Cl. Chloride's oxidation number is -1.Ca +2 Cl -1Ca 1 Cl 2 (Switch the two numbers)Ca1Cl2 HOWEVER if there's only one of an element, don't write the 1CaCl2
The chemical formula for potassium metaperiodate is KIO4. The oxidation number of potassium is +1.
