Consider the following elements A, B, C and D and their outer electronic configurations are

ns^2np^1

ns^2np^3

ns^2np^4

and

ns^2np^5

respectively. Element E also has same outer electronic configuration like D but shows only single oxidation state (-1). If element A, B, C and D belong to same period as that of sodium. Consider the following compounds.


(i) $\text{CE}_4$	(ii) $\text{BD}_2\text{E}_3$	(iii) $\text{DE}_3$	(iv) $\text{CE}_2$
(v) $\text{BD}_3\text{E}_2$	(vi) $\text{C}_2\text{E}_2$	(vii) $\text{DE}$	(viii) $\text{A}_2\text{D}_6$

Then calculate the value of "

x + y

", (where

x

and

y

are total number of polar and non-polar compounds).
