Apparent charge on atom in a molecule is:
Correct answer: C. Oxidation number
- A. Valency
- B. Coordination number
- C. Oxidation number
- D. Charge number
Explanation
The correct answer is Option C: Oxidation number. The oxidation number represents the apparent charge on an atom in a molecule, assuming that the electrons in a bond are assigned to the more electronegative atom. This concept helps in understanding redox reactions and electron transfer. Option A: Valency is incorrect because it describes the number of bonds an atom can form, not its charge. Option B: Coordination number is incorrect as it refers to the number of atoms bonded to a central atom, not an atom's charge. Option D: Charge number is incorrect because it relates to the quantized electric charge of particles, not the effective charge in a molecular context.

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.
