Chapter Summary

--- PAGE 1 --- Unit 4 The d- and f- Block Elements Objectives After studying this Unit, you will be able to * learn the positions of the d- and f-block elements in the periodic table; * know the electronic configurations of the transition (d-block) and the inner transition (f-block) elements; * appreciate the relative stability of various oxidation states in terms of electrode potential values; * describe the preparation, properties, structures and uses of some important compounds such as K₂Cr₂O₇ and KMnO₄; * understand the general characteristics of the d- and f-block elements and the general horizontal and group trends in them; * describe the properties of the f-block elements and give a comparative account of the lanthanoids and actinoids with respect to their electronic configurations, oxidation states and chemical behaviour. Iron, copper, silver and gold are among the transition elements that have played important roles in the development o…
