Dear Student,
(a) The element below sodium in the same group would be expected to have a lower (lower / higher) electro-negativity than sodium and the element above chlorine would be expected to have a higher  (lower/ higher ) ionization potential than chlorine.
(b) On moving from left to right in a given period, the number of shells remains the same (remains the same/increases decreases).
(iii) On moving down a group, the number of valence electrons remains the same (remains the same /increases/decreases).
(iv) Metals are good reducing agent (oxidising agent/reducing agent) because they are electron donors (acceptors/ donors).
