In-text question

1. Silver atom has completely filled d orbitals in its ground state. How can you say that it is a transition element?

2. In the series Sc (Z = 21) to Zn (Z = 30), the enthalpy of atomization of zinc is the lowest, i.e., . Why?

3. Which of the 3d series of the transition metals exhibits the largest number of oxidation states and why?

4. The value for copper is positive (+0.34V). What is possibly the reason for this? (Hint: consider its high and low )

5. How would you account for the irregular variation of ionization enthalpies (first and second) in the first series of the transition elements?

6. Why is the highest oxidation state of a metal exhibited in its oxide or fluoride only?

7. Which is a stronger reducing agent or and why?

8. Calculate the ‘spin only’ magnetic moment of ion (Z = 27).

9. Explain why ion is not stable in aqueous solutions?

10. Actinoid contraction is greater from element to element than lanthanoid contraction. Why?
