Sum of oxidation numbers of all the molecules in a neutral atom is
Correct answer: D. 0
- A. Unity
- B. Negative
- C. 1
- D. 0
Explanation
Option D is correct since in a neutral atom the charge is zero. So if we equate all the oxidation numbers we get zero.Option A is incorrect since the charge on a neutral atom cannot be equal to unity.Option B is incorrect since the charge on a neutral atom cannot be negative.Option C is incorrect since the charge on a neutral atom cannot be 1.

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.
