1.	The largest oxidation number exhibited by an element depend on its outer electronic configuratoin withwhich of the following outer eletronic configuration the element will exhibit largest oxidation number ?
Answer» Solution :Hishest O.N of any transition ELEMENT =(n-1) d electrons + ns electrons therefore larger the number of electrons in the 3d orbitals higher is the maximum O.N (a) `4d^(1) 4S^(2)=3 , (b) 3d^(3) 4s^(2)=3+2=5 , (c ) 3d^(5)4s^(1)=5+1=6 and (d) 3d^(5)=5+2=7` THUS option (d) is correct
