Answer: Fluorine contains seven valence electrons. It needs one more electron to complete its octet. The oxidation number is 1- and indicates fluorine will gain or share one electron when it combines with another atom to become a more stable compound.

6 because the number of valence electrons is always the ones-place of any two-digit group number. So an element in group 18 would have 8 valence electrons
Hope this helps!
In a voltaic cell there are two electrodes: anode and cathode.
On the cathode, the reaction that occurs is reduction, which means that the metal gains electrons.
On the anode the reaction is oxidation, which means that the metal loses electrons.
In this voltaic cell the reaction on the anode is:
Zn --> Zn 2+ + 2e-, i.e. option C.
Answer: option C.
