These are the rules of assigning oxidation numbers in compounds (in order of priority):
1. All group 1 metals have an ON of +1
2. Group 2 metals have an ON +2
3. Al is in group 3 and so has an ON of +3
4. O has an ON of -2 (except in peroxides where it is -1)
5. H has an ON of +1 (except in metal hydrides where it is -1)
6. F has an ON of -1
7. Cl has an ON of -1 except in compounds with O and F
Therefore, to assign C a oxidation number you have to work out the rest first as all the oxidation numbers in the compound have to make 0.
Mg has a ON of +2. (rule 2)
O has an ON of -2 (rule 4) but there are 3 O's and so you have to do 3x-2 = -6
Therefore, you have -6 (O) + 2 (Mg) = -4
Therefore, the ON of C must be +4 to make it equal to 0.

WHAT IS OXIDATION NUMBER OF MGCO3?
Magnesium and carbonate are divalent.
What is the oxidation number for carbonate and barium?
The oxidation number for carbonate is -2, as it is composed of one carbon atom with a formal charge of +4 and three oxygen atoms each with a formal charge of -2. The oxidation number for barium is +2, as it is a group 2 element in the periodic table, meaning it typically forms 2+ cations.
What are the oxidation numbers of magnesium in magnesium dichromate?
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.
In the compound MgO magnesium has an oxidation number of .?
+2
What is the oxidation number in carbon and sulfur in CO?
The oxidation number is + for C and -2 for O.
What is the oxidation number of magnesium carbonate?
+2 for Mg, +4 for C, -2 for each O in MgCO3
WHAT IS OXIDATION NUMBER OF MGCO3?
Magnesium and carbonate are divalent.
What is the oxidation number in Carbonate?
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.
What is the oxidation number of carbon in Hydrogen carbonate?
The oxidation number of carbon in hydrogen carbonate (HCO3-) is +4. This can be determined by considering the oxidation numbers of the other elements in the compound (hydrogen and oxygen) and applying the rule that the sum of oxidation numbers in a compound must equal zero.
What is the oxidation number of carbon in carbonate?
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.
What is the oxidation number of carbon in carbonic acid?
I believe K2CO3.
What is the Oxidation number of calcium carbonate?
The oxidation number of calcium in calcium carbonate (CaCO3) is +2. The oxidation number of oxygen is -2. By comparing the charges in the compound, you can deduce that the oxidation number of carbon in calcium carbonate is +4.
What is the simple oxidation number for magnesium?
Magnesium is in the group 2. 0 is the lowest oxidation number for it.
What is the oxidation number for carbonate and barium?
The oxidation number for carbonate is -2, as it is composed of one carbon atom with a formal charge of +4 and three oxygen atoms each with a formal charge of -2. The oxidation number for barium is +2, as it is a group 2 element in the periodic table, meaning it typically forms 2+ cations.
What is the number of electrons and oxidation number of magnesium?
Singl atom has 12 electrons. Oxidation number of it is +2.
What is the oxidation number of magnesium sulfide?
The oxidation number of magnesium in magnesium sulfide is +2. Sulfur typically has an oxidation number of -2 in ionic compounds.
What is the oxidation number of sodium carbonate?
The oxidation number of sodium (Na) in sodium carbonate (Na2CO3) is +1. The oxidation number of oxygen (O) is -2, and the oxidation number of carbon (C) is +4. Therefore, the overall compound has a charge of 0.
