Want this question answered?
The oxidation number of Calcium (Ca) is +2
+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.
-1 for Carbon (in carbide) and +2 for Ca
Ca is 2+ and P is 3-

The only oxidation number is 2+.
-1 for Carbon (in carbide) and +2 for Ca
Ca is 2+ and P is 3-
+2 for Ca in its compounds
+2 for Ca, +6 for Cr, -2 for each O
0 for the elemental form +2 in its compounds
The oxidation number of Ca is 0 in its elemental form and is +2 in its compounds.
They do not. The group 2 elements, Be, Mg, Ca etc, have oxidation numbers of +2.
Of course not. No change in neutrons. Number of electrons decrease
