Atomic numbers of few elements as 56,57,72,89,49,38,46 among then No of S-block elements = X No of P-block elements =Y No of d-block elements =Z Then X +Z - Y value is

Assertion (A): s- block elements can form ionic hydrides. Which on electrolysis in fused state give H_(2) gas at cathode. Reason (R) : s-block elements have low IE and low EN as compared to p-block elements.

For the molecule MA_(2)L_(n) (where A is number of single bonded surrounding atoms, L indicates lone pair and n is the number of lone pair and M is the central atom of s or p block element). The possible range of 'n' is :
