FAQs on The d & f-Block Elements in One Shot (NCERT) - 1 Video Lecture - Chemistry Class 12 - NEET

1. What are d-block elements?
Ans. The d-block elements, also known as transition elements, are a group of elements in the periodic table that have partially filled d orbitals in their atomic or ionic states. They are located in the middle of the periodic table, between the s-block and p-block elements.
2. How are d-block elements different from f-block elements?
Ans. The main difference between d-block and f-block elements lies in their electron configurations. D-block elements have partially filled d orbitals, while f-block elements have partially filled f orbitals. Additionally, d-block elements are transition elements, whereas f-block elements are known as inner transition elements.
3. What is the significance of d-block elements?
Ans. D-block elements have several important properties and applications. They exhibit variable oxidation states, form colored compounds, and are often good catalysts. These elements are commonly used in the production of steel, as well as in various industrial processes, such as the Haber process for ammonia synthesis.
4. How are d-block elements classified?
Ans. D-block elements are classified into four series: 3d (Sc to Zn), 4d (Y to Cd), 5d (La to Hg), and 6d (Ac to Cn). These series are named after the first element in each series. Each series corresponds to a specific period in the periodic table and represents the filling of the d orbitals.
5. What are some common properties of f-block elements?
Ans. Some common properties of f-block elements include their tendency to exhibit multiple oxidation states, the ability to form complex compounds, and the presence of unique magnetic properties. They are commonly used in various applications, such as nuclear energy production and as catalysts in chemical reactions.
