The oxidation number of Calcium (Ca) is +2
C10H12CaN2Na2O8
2 Ca + 2O2 = 2(CaO2)
+4 oxygen has an oxidation of -2, so do 3 times -2=-6, i believe Ca is a +2 and you must get the numbers to equal 0. so the answer is a +4
Oxidation number is plus two. It is common to every ion of Ca.

Ca(ClO4)2 is calcium perchlorate.It is more often referenced as calcium perchlorate tetrahydrate = Ca(ClO4)2 . 4 (H2O)
Ca+O2>CaO2

The only oxidation number is 2+.
-1. In simple inorganic compounds other than peroxides and superoxides, oxygen almost always has an oxidation number of -2, but since calcium cations always have an oxidation number of +2, in this compound, the two oxygen atoms must have only -1 charge each. This compound is calcium peroxide, one of the exceptions noted above.
-1 for Carbon (in carbide) and +2 for Ca
+2 for Ca in its compounds
Ca is 2+ and P is 3-
