6 Which of the elements has seven electrons in d-subshell? Zn Co Cu Fe
7 d-d transition cannot be observed in Cr Cu Mn Zn
8 which of the following is a typical transition metal? Sc Y Ra Co
9 which one pair has the same oxidation state of-Fe? FeSO4 and FeCl4 FeCl4and FeCl3 FeSO4 and FeCl2 Fe2(SO4)3 and FeSO4
10 Which pair of transition elements shows abnormal electronic configuration? Sc and Zn Cu and Sc Zn and Cu Cu and Cr
11 Oxidation state of Mn' in KMnO4. K2MnO4, MnO2 and MnSO4 is in the order +7.+6.+2,+4 +6,+7,+2,+4 +7. +6.+4.+2 +4, +6, +7,+2
12 which of the following d blocks element can showthe highest oxidation number is its ompound Chromium iron Copper Manganese
13 In [Ti (H2O)]3+ which colour is transmitted Yellow Blue and red Blue and yellow red and yellow
14 In the electronic configuration of Cr one electron from 4s sub-shell is transferred to 3d sub-shell because The 3d orbital is of lower energy than 4s The half-filled d-subshell is more stable than 4 electrons having d-subshell The 4s orbital is of equal energy to 3d orbital 6 unpaired electron make Cr more paramagnetic
