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.
-1 for Carbon (in carbide) and +2 for Ca
Of course not. No change in neutrons. Number of electrons decrease
The oxidation number of Ca is 0 in its elemental form and is +2 in its compounds.

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.
The oxidation number of Ca in CaO2 is +1. This is because the oxidation number of O is -2, and since there are two O atoms in CaO2, the overall charge contributed by the oxygen atoms is -4 (2*-2). Therefore, the oxidation number of Ca must be +1 to balance the charges and make the compound neutral.
The oxidation number of Ca in CaC2O4 is +2 because Ca, a group 2 element, typically has a +2 oxidation state in compounds. The oxidation number of C in C2O4 is +3 because the overall charge of the oxalate ion is -2, and there are two C atoms, each with an oxidation state of +3 to balance the charge.
The oxidation number of calcium (Ca) in CaF2 is +2. This is because fluorine (F) typically has an oxidation number of -1, and the overall charge of CaF2 is neutral. Since there are two fluorine atoms each with a -1 charge, the calcium atom must have a +2 oxidation number to balance the charges.
The sum of the oxidation numbers is zero for the compound.
