Group 18 or noble gases
0- any element by itself has an oxidation number of 0.
Magnesium is in the group 2. 0 is the lowest oxidation number for it.
the oxidation number is 0
It is in the first group. It shows only -1 number.
The maximum oxidation number is theoretically equal to the number of valence electrons. For example the oxidation number of chlorine among different compounds can vary from -1 to +7. An exception for this is fluorine, which only have -1 and 0 as its oxidation numbers.
0- any element by itself has an oxidation number of 0.
Noble gas have 0 Oxidation number. That's because they do not form ions.
Magnesium is in the group 2. 0 is the lowest oxidation number for it.
the oxidation number is from 0 to 2+
the oxidation number is 0
It is in the first group. It shows only -1 number.
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....

Cl has an oxidation number of -1 because it is in the group 7a. -1*6 = -6 K has an oxidation number of +1 and there are three of them. -6+3+x = 0 The oxidation number of Co is +3.
Xe when it is not in a compound has an oxidation number of 0
Xe when it is not in a compound has an oxidation number of 0
The molecular formula should be CBr4. The oxidation numbers are -1 for each Br, +4 for C.
