+3 for each Al; +4 for each C; -2 for each O
The oxidation number of carbon in carbonate (CO3^2-) is +4. Oxygen has an oxidation number of -2, so the three oxygen atoms contribute a total of -6. To balance the charge of -2 for the entire carbonate ion, the carbon atom must have an oxidation number of +4.
Metallic aluminium has the oxidation number zero. In compounds in the form of ions, it takes the oxidation number +III.Metallic aluminium has the oxidation number zero. In compounds in the form of ions, it takes the oxidation number +III.
+2 for Mg, +4 for C, -2 for each O in MgCO3
Thallium has an oxidation number of +1. Therefore, the formula for thallium carbonate would be Tl2CO3.
Aluminium carbonate solution is usually colorless.

Thallium has an oxidation number of +1. Therefore, the formula for thallium carbonate would be Tl2CO3.
Magnesium and carbonate are divalent.
From '0' to '3'. Elemental aluminium is in oxidation state zero (0). When it combines with oxygen to form aluminium oxide , it 'looses' its three outermost electrons to oxygen. Hence aluminium metal becomes the aluminium cation (Al^3+), which is oxidation state '3'.
Aluminium carbonate solution is usually colorless.
Aluminium emit 3 electrons. It makes aluminium ion.
Na2C03 Oxidation number of Na = + 1 Oxidation number of O=-2, Oxidation number of C=2x1+x+3(-2)=0 so x=4
The oxidation number of carbon in carbonate (CO3^2-) is +4. In the carbonate ion, each oxygen atom has an oxidation number of -2, so the overall charge of the ion is -2. This means the oxidation number of carbon must be +4 to balance the charges in the compound.
