-1 for Carbon (in carbide) and +2 for Ca
The oxidation number of Ca is 0 in its elemental form and is +2 in its compounds.
In CaC2, the oxidation number of the Ca atom is +2 because it is a group 2 element. The oxidation number of the C atom is -2 because it typically forms covalent bonds with other elements, resulting in a formal charge of -2 on each C atom in CaC2.
The oxidation number of Calcium (Ca) is +2
The oxidation number of calcium (Ca) is +2 and the oxidation number of phosphorus (P) is -3. Therefore, in Ca₃P₂, the oxidation number of calcium is +2 and the oxidation number of phosphorus is -3.
In CaSO4, the oxidation number of Ca is +2, the oxidation number of S is +6, and the oxidation number of O is -2.

The oxidation number of Calcium (Ca) is +2
The oxidation number of calcium (Ca) is +2 and the oxidation number of phosphorus (P) is -3. Therefore, in Ca₃P₂, the oxidation number of calcium is +2 and the oxidation number of phosphorus is -3.
CaC2 It is also called Calcium Acetylide which describes the structure better. It forms a chain with a triple bond between the Carbon atoms -Ca-C---C-Ca-C---C-Ca- etc.
In CaSO4, the oxidation number of Ca is +2, the oxidation number of S is +6, and the oxidation number of O is -2.
CaC2+O2------> Ca+ CO2
Of course not. No change in neutrons. Number of electrons decrease
The oxidation value (number) of C atom in carbide (not corbide) is -1, and of Ca always +2. This makes one Ca reacting with two C atoms in forming CaC2.Calcium Carbide is a common but improper name for CaC2.It's proper name is Calcium Acetylide.In Calcium Acetylide there are three covalent bonds joining the Carbon atoms, andthe forth bond of each Carbon go to Calcium forming an ionic bond.Crystal structure :The common crystalline form at room temperature is tetragonal, a distorted rock salt structure with the C22− units lying parallel.(Cf. 'Related links' for ionic picture)
The only oxidation number is 2+.
The oxidation state of an individual carbon atom in CaCO3 is +4. This is because the oxidation state of Ca is +2, and the oxidation states of O are typically -2. The sum of the oxidation states for CaCO3 must equal 0, so the oxidation state of carbon in this compound must be +4.
The oxidation number for Sulfur (S) in CaSO3 is +4. This is because Calcium (Ca) has an oxidation number of +2 and Oxygen always has an oxidation number of -2. By setting up the equation Ca(+2) + S(x) + 3O(-2) = 0, we find that x = +4 for Sulfur.
