1.	An element 11X23 forms an ionic compound with another element ‘Y’. Then the charge on theion formed by X is [ ]a) +1 b) +2 c) -1 d) -2
Answer» udent,◆ Answer -(a) +1◆ EXPLAINATION -For element X, ATOMIC NUMBER is 11.Electronic CONFIGURATION of X would be E.C. = 1s2 2s2 2p6 3s1 = [Ne] 3s1Element X has only 1 electron in its outermost orbit, THEREFORE it donates this e- to element Y forming X+ cation.Hence, charge on ion formed by X is +1.Hope this helps you
