Question

X , Y, Z ,A,E are the five elements from periodic table in which A have highest Ionisation energy

whereas X have lowest one. Both Z and E are non metals but electronegativity of Z is greater than E. A is

smallest element. X, E and Y all have equal number of shells. Y is smaller than X. Z,A and E have equal

valency. On the basis of above information answer the following

(i)Which three elements are in the same group

(ii)Between X and E which have greater Electronegativity .

(iii)Between E and Z which have higher ionisation energy.

(iv)Between Z and X which have more no of shells.​
