Q. Objectives of transition elements of the f-block?
After studying this unit you should be able to:
- distinguish between transition and inner-transition elements,
- describe the terms lanthanides and actinides,
- evaluate the electronic configurations of lanthanide and actinide ions from the electronic configurations of free atoms,
- show the ways in which actinide elements resemble their lanthanide Eongeners,
- show the ways in which the actinides resemble more closely d-block transition elements,
- illustrate lanthanide and actinide contraction,
- Explain general characteristics of lanthanide and actinide elements and bring out periodicity in their properties.
