+2 for Mg, +4 for C, -2 for each O in MgCO3
Magnesium is in the group 2. 0 is the lowest oxidation number for it.
The oxidation number of magnesium in magnesium sulfide is +2. Sulfur typically has an oxidation number of -2 in ionic compounds.
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.
The oxidation number of magnesium is +2. Any other for this element would be energetically unfavorable and unstable.
In magnesium bromide (MgBr2), magnesium has an oxidation number of +2 and each bromine atom has an oxidation number of -1. This is because magnesium typically forms 2+ cations, while bromine forms 1- anions.
Magnesium and carbonate are divalent.
Magnesium is in the group 2. 0 is the lowest oxidation number for it.
Singl atom has 12 electrons. Oxidation number of it is +2.
The oxidation number of magnesium in magnesium sulfide is +2. Sulfur typically has an oxidation number of -2 in ionic compounds.

In magnesium bromide (MgBr2), magnesium has an oxidation number of +2 and each bromine atom has an oxidation number of -1. This is because magnesium typically forms 2+ cations, while bromine forms 1- anions.
Thallium has an oxidation number of +1. Therefore, the formula for thallium carbonate would be Tl2CO3.
In compounds, magnesium has a +2 oxidation state; in most but not quite all compounds, oxygen has a -2 oxidation state. In peroxides, oxygen has a -1 oxidation state. In oxygen fluorides, oxygen has positive oxidation states.
The most common oxidation number of magnesium is +2.
