FAQs on NCERT Solutions for Class 12 Chemistry Chapter 8 - The d and f-Block Elements
1. How Helpful is the NCERT Solution for Understanding f and b Block Elements?
Expert teachers in Chemistry formulate the NCERT solution for f and b block elements. This material is of great help for students appearing in the board exams as it will clear all the doubts based on the fundamentals of the chapters through examples, diagrams, and illustrations.
All important topics related to electronic configuration, oxidization, and chemical reactivity of inner transition metals are delved in detail. The students will be able to learn the positions of d- and f- block elements in the periodic table.
Apart from the general characteristics, the students will also learn about topics like Trends instability of higher oxidization states and trends in M3+/M2+ Standard Electrode Potential.
2. Provide Some of the Important NCERT Questions on f and b Block Elements.
Some of the critical questions for both short and very short questions from f and b block elements are given below.
Explain why Cu+ ion is not stable in aqueous solution.
What is the stronger reducing agent Cr2+ or Fe2+, and why?
Why is the highest oxidization state of metal exhibited in its oxide and fluoride only?
Which of the 3d series of transition metals exhibits the largest numbers of oxidized states and why?
The silver atom has filled the d orbit (4d10) in its ground state, then how can you state that it is a transition element?
3. What are the Important NCERT Topics and Subtopics of Chapter f and b Block Elements?
The important NCERT topics and subtopics for the d and f block chapter are given below:
Position in the periodic table.
Electronic configuration of the d block element.
General properties of Transition elements (d block).
Some important compounds of transition elements.
The Lanthanoids.
The Actinoids.
Some application of d block and f block elements.
The NCERT solutions cover all the chapters through exercises and detailed illustrations. Nearly 38 questions are solved extensively by expert teachers that generate improved understanding. Apart from this, there is also a section of solved examples that helps the students in clarifying the concept of d and f block elements.
4. How do you define f block Class 12 Chapter 8 Chemistry?
The elements that make up the f-block are those in which the 4 f and 5 f orbitals are gradually filled in the last two long periods; these elements are official members of group 3, from which they were separated to create the f-block of the periodic table. For additional modules regarding the same, please visit the Vedantu site (vedantu.com) or download the Vedantu app. Practice all the related problems diligently in order to grasp the concepts well.
5. Where would you group Lanthanum in the f block?
Lanthanum cannot be grouped in the f block as it is a d block element. Lanthanum is the first element in the third transition series, and it begins to fill the 5d orbitals. As a result, the configuration is [Xe]5d1 6s2. Only the following element (cerium) fills the 4f orbitals. Hence it will be grouped among the d block elements of the periodic table. Modules relating to this topic or other topics covered in this chapter may be found on the Vedantu website (vedantu.com) or the Vedantu app.
6. Which is the best Solution book for NCERT Class 12 Chapter 8 Chemistry?
The best solution book is of Vedantu as it is easily accessible and free of charge on the Vedantu website. Click on it to obtain the PDF version of the NCERT Class 12 Chemistry Chapter 8 answers. If you want further assistance in better-comprehending topics and achieving high scores in examinations and admission exams, the Vedantu website and app can assist you.
7. Why do we mention f block elements below?
The f-block elements are 28 elements broad, and if they were placed in their atomic number position alongside the transition metals, the periodic table would be too wide to fit on normal A4 paper or a page in an instructional book, therefore they were positioned below the other groups. Hence it is mentioned in a separate manner below the other elements. Modules connected to this topic or other topics in this chapter may be found on the Vedantu website or the Vedantu app.
8. What are the challenging chapters in Class 12 Chapter 8 Chemistry?
Each chapter poses its own set of unique challenges in Chemistry but there are few chapters that pose multiple hindrances which is common for most students. In the syllabus of NCERT Class 12 Chemistry, the p block elements are considered a tougher chapter when compared to the other chapters of the subject. Hence it is important to study this chapter with patience and caution and grasp all the concepts well.
