Identify each of the following half-reactions as either an oxidation half-reaction or a reduction half-reaction. half-reaction identification Ag (aq) e-Ag(s) reduction Cu (aq)Cu2 (aq) e- oxidation (2) Write a balanced equation for the overall redox reaction. Use smallest possible integer coefficients.

where are the choice options?

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
