Match the properties given in Column I with the metals given in Column – InterviewSolution

1.	Match the properties given in Column I with the metals given in Column II.
Answer» Solution :A. `Cu^(+) = 3d^(10)` which is very stable configuration DUE to full-filled orbitals. Hence, removal of second electron requires very high ENERGY. B. `Zn^(2+) = 3d^(10)` which is very stable configuration. Hence, removal of THIRD electron reuqires very high energy. C. Metal carbonyl with formula `M(CO)_(6)` is `Cr(CO)_(6)`. D. Nickel is the element with highest heat of atomisation.
