Someone check my answers asap please, will give brainliest!! Find oxidation and reduction half-reactions to this equation

Oxidation: K (s) --> K+ (aq) + e
Reduction: Cu2+ + 2e --> Cu (s)

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: )
