-2 for each O, +1 for each K and +6 for each Cr
the oxidation number is 0
0 because all compounds have an oxidation number of 0. It's the ions (fe S O) that have oxidation numbers, The sum of these oxidation numbers always = 0 in a compound and hence a compound has a oxidation number of 0. :-) hope this helped....
Xe when it is not in a compound has an oxidation number of 0
the oxidation number is from 0 to 3+
Oxidation number of a free element is 0. Ex: Ag 2= 0
the oxidation number is from 0 to 2+
the oxidation number is 0

0- any element by itself has an oxidation number of 0.
there are two for silicone.those are 0 and 4.Atomic silicon has oxidation number 0. It forms a wide variety of compounds, specially with oxygen. In these compounds, the oxidation number of silicon can vary from 0 to +4.
Atomic oxygen has oxidation number 0. Molecular oxygen also has 0 as oxidation number. It would be the same for five oxygen molecules as well.
the oxidation number is 0
The oxidation number of Mn in the molecule Mn2 would be 0.
