FAQs on The d & f block Elements Video Lecture - Chemistry Class 11 - NEET

1. What are the d-block and f-block elements?
Ans. The d-block and f-block elements are groups of elements in the periodic table. The d-block elements, also known as transition metals, are located in the middle of the periodic table and include elements from group 3 to group 12. The f-block elements, also known as inner transition metals, are located at the bottom of the periodic table and include the lanthanides and actinides.
2. What are the properties of d-block elements?
Ans. The d-block elements have several characteristic properties. They are typically good conductors of heat and electricity, have high melting and boiling points, and form colored compounds. They also exhibit variable oxidation states and can form complex ions. Furthermore, d-block elements often have magnetic properties and show catalytic activity.
3. What are the properties of f-block elements?
Ans. The f-block elements share some common properties. They have high melting and boiling points, exhibit variable oxidation states, and form complex ions. Additionally, f-block elements are typically radioactive and have large atomic sizes. They are also known for their unique magnetic properties and ability to absorb and emit light.
4. How do d-block elements contribute to the periodic table?
Ans. D-block elements play a crucial role in the periodic table. They fill the middle portion of the table and bridge the s-block and p-block elements. D-block elements have partially filled d orbitals, which allow them to exhibit a wide range of chemical behaviors. Their ability to form multiple oxidation states and complex ions makes them important in various chemical reactions and industrial processes.
5. What are some applications of d-block and f-block elements?
Ans. D-block and f-block elements find applications in various fields. Transition metals (d-block elements) are used in catalysis, electronics, construction, and manufacturing of alloys. They are also essential components of many biological systems, such as enzymes. Inner transition metals (f-block elements) have applications in nuclear energy, medicine (e.g., cancer treatment), and magnetic technology (e.g., MRI machines).
