उत्तर
Transfer of electron(s) is involved in the formation of an electrovalent bond. The electropositive atom undergoes oxidation, while the electronegative atom undergoes reduction. This is known as a redox process.
Oxidation: In the electronic concept, oxidation is a process in which an atom or ion loses electron(s).
Zn → Zn2+ + 2e-
Reduction: In the electronic concept, the reduction is a process in which an atom or ion accepts electron(s).
Cu2+ + 2e-→ Cu
