NCERT Solutions class 12 Chemistry The d and f block elements part 1
After completing the chapter, for the preparation of session — exam, you are suggested to do the three tests of Level 1, Level 2 and Level 3 and discuss it with your classmates and school teacher for answers. Dear all, Tiwari academy group is doing excellent job for students and as well as teachers. Easy concepts, easy notes and more importantly user friendly Thank you all. We are working for the same and updating all the solutions of Physics and Chemistry of Class Before October, all the updates will be done. Thanks for all really helpful notes in all subjects of class
Going through the solutions provided on this page will help you to know how to approach and solve the problems. Question 1. Silver atom has completely filled d-orbitals 4d 10 in its ground state. How can you say that it is a transition element? Question 2.
Silver atom has completely filled d orbitals 4d 10 in its ground state. How can you say that it is a transition element? Hence, it is a transition element. Hence, the intermetallic bonding is weakest in zinc. Therefore, enthalpy of atomisation is lowest. Which of the 3d series of the transition metals exhibits the largest number of oxidation states and why?

In this chapter, students shall first deal with the electronic configuration, occurrence and general characteristics of transition elements with special emphasis on the trends in the properties of the first row 3d transition metals along with the preparation and properties of some important compounds. This will be followed by consideration of certain general aspects such as electronic configurations, oxidation states and chemical reactivity of the inner transition metals. After studying this chapter, students 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. The topics and sub-topics in Chapter 8 The d and f Block Elements are given below. We cover all exercises in the chapter given below
These ncert book chapter wise questions and answers are very helpful for CBSE board exam. To what extent do the electronic configurations decide the stability of oxidation states in the first series of the transition elements? Illustrate your answer with examples. What may be the stable oxidation state of the transition element with the following d electron configurations in the ground state of their atoms: and? Name the oxometal anions of the first series of the transition metals in which the metal exhibits the oxidation state equal to its group number. What is lanthanoid contraction?
