The oxidation number is +2 for Ni.
The oxidation number for CO3 with a charge of -2 is 2.
The oxidation number of carbonate ion (CO3) is -2. Each oxygen atom has an oxidation number of -2, and the sum of the oxidation numbers in the ion must equal the charge of the ion, which is -2.
There is no compound by the name nickel(I) carbonate. Nickel(II) carbonate is however NiCO3
The oxidation number of C in CO3^2- is +4. Each oxygen atom has an oxidation number of -2, and since the overall charge of the carbonate ion is 2-, the carbon atom must have an oxidation number of +4 to balance the charge.
Using the periodic table of elements you can find the oxidation number of NaHCO3. Na has a charge of +1 so it's oxidation number is +1. H has a charge of +1 so again, the oxidation number is +1. CO3(carbonate) has an oxidation number of -2. As far as I know, you can find the oxidation number for CO3 because all charges together come out to be zero. With Na and H adding up to 2, CO3 can be seen to be -2. Also, CO3 is -2 because it's Lewis structure is two electrons short from being complete.
The oxidation number for CO3 with a charge of -2 is 2.
there are two ions. Ni and CO3.
The oxidation number of carbonate ion (CO3) is -2. Each oxygen atom has an oxidation number of -2, and the sum of the oxidation numbers in the ion must equal the charge of the ion, which is -2.
+2 for Mg +4 for C -2 for each O

With the 2 oxidation state. NiCO3
The oxidation number of copper (Cu) in CuCO3 is +2. Oxygen typically has an oxidation number of -2, and the overall charge of the carbonate ion (CO3) is -2. Therefore, the oxidation number of copper is determined to be +2 in this compound.
Nickel carbonate is NiCO3 with the molar mass 118,7 g.
The oxidation number of carbon (C) in CO3^2- is +4. This is because the sum of the oxidation numbers in the carbonate ion must equal its charge of -2, and oxygen is typically assigned an oxidation number of -2.
The oxidation number of each copper (Cu) atom in CuCO3 is +2. The oxidation number of the oxygen (O) atoms in the carbonate ion (CO3) is -2, and the overall charge of the carbonate ion is -2.
