(i) ‘M’ and ‘N’ belong to the same period but group I and II respectively. N is smaller than M as the atomic size decreases on moving from left to right across the Periodic Table. 

(ii) M is more metallic than ‘N’ because metallic character decreases from left to right as tendency to lose electrons decreases due to decrease in atomic size. 

(iii) The valencies of M and N are 1 and 2 respectively, valency across the period first increases then decreases. 

(iv) MCl and NCl2.
