Correct statements about transition metals are that they:A. form complexB. show variable oxidation statesC. show magnetic propertiesD. do not from coloured compounds |
|
Answer» Correct Answer - ABC the great tendency of transition material ion to form complex is due ,(i) small size to the atoms and ions(ii) high nuclear charge and (iii) availability of vacant d-suitable energy to accept lone pair of electrons donates by ligands. (B) The existence of the transition element in different oxidation state is due to the participation of inner `(n-1)` d-electrons in addition to outer ns-electrons because , the energies of the ns and (n-1) d-sub-shells are nearly same. (C ) The transition metals show magnetic properties due to presence of number of unpaired electrons in d-orbital. (D) Most the transition metal ion are coloured, because they have unpaired electrons which can undergo d-d transition in presence of ligands. |
