2Na(s) + Cl2(g) ==> 2NaCl(s)
Na on the left has an oxidation state of zero.(ALL elements in the free state are zero oxidation state or zero charge). On the right it is +1 for each Na atom. Change in oxidation state is zero to +1 or gain of 1 e per atom.
Cl on the left has an oxidation state of zero. On the right it is -1 for each atom. Change in oxidation state is zero to -1 or gain of 1 e per atom.
2. Na^+
3. Cl^-
4. NaCl named sodium chloride.
