All of the following statements about (oxidation) state are correct EXCEPT:
Correct answer: D. Xenon (Xe) can show maximum oxidation state +6 in its compounds
- A. It is apparent charge on an atom in a compound
- B. Its value is either zero, positive or negative
- C. It can be variable
- D. Xenon (Xe) can show maximum oxidation state +6 in its compounds
Explanation
Oxidation state or oxidation number, is the hypothetical charge of an atom if all of its bonds to other atoms were fully ionic. It describes the degree of oxidation of an atom in a chemical compound.

About Electrochemistry
Electrochemistry describes electron transfer through oxidation and reduction, identifies oxidizing and reducing agents, and applies oxidation numbers to balance redox equations. It also covers electrode potential and the standard hydrogen electrode, which provides the reference for comparing the reduction tendencies of other electrodes.
