+1 for Cs
+5 for As
-2 for O
100 will be oxidation no.in Fe2O3.
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....
Silver is a rare element. Generally it shows 0and +2 oxidation numbers.
Carbon is a pblock element. It shows -4 to +4 oxidation numbers.
0.
Yes, inert gases like neon have zero oxidation numbers. This is why they are non-reactive.
In a neutral compound, the sum of the oxidation numbers of the atoms in the compound is zero.
The oxidation numbers for the atoms in the ionic compound KCl are K+1 and Cl-1.

As with any other element, the oxidation number of Cr depends on whether and how it is chemically bonded. The oxidation number of pure elements is arbitrarily defined to be 0. In compounds, Cr has oxidation numbers of +2, +3, and +6, depending on the compound.
0 they are neutral
sum will be zero
0.
The compound has no charge. This means that the positive oxidation numbers must equal the negative oxidation numbers. Cl has an oxidation number of -1. Therefore, Zn must have an oxidation number of +1.
