FAQs on D and F Block Elements NEET 2025 Mock Test – Free Online Chapter Practice

1. What are d and f block elements?

D block elements are those elements in which the last electron enters the d-orbital of the penultimate shell, typically found in Groups 3 to 12 of the periodic table, also known as transition elements. F block elements, also called inner transition elements, are those elements in which the last electron enters the f-orbital; these are the lanthanides (atomic numbers 58–71) and actinides (atomic numbers 90–103). Both blocks are significant in NEET Chemistry for their unique properties and applications.

2. What are the f block elements?

F block elements are lanthanides and actinides, placed separately at the bottom of the periodic table. Lanthanides include elements from atomic number 58 (Cerium) to 71 (Lutetium), while actinides cover atomic number 90 (Thorium) to 103 (Lawrencium). These elements are known for their variable oxidation states and are often called inner transition metals.

3. Give examples of d-block elements.

Typical d-block elements include iron (Fe), copper (Cu), nickel (Ni), chromium (Cr), and zinc (Zn). They are located in Periods 4 to 7 and Groups 3 to 12 of the periodic table and commonly exhibit variable oxidation states, colored compounds, and catalytic properties.

4. What are some tricks to remember the d and f block elements?

To memorize d and f block elements rapidly, use mnemonics for each row. For example, for 3d series: Sc Ti V Cr Mn Fe Co Ni Cu Zn, try "Saint Tiger Viciously Crushed Many Ferocious Cows Near Cute Zebras". For lanthanides, associate each element with a keyword or visual image. Repeated table writing and practicing with NEET mock quizzes also reinforces recall.

5. Why are d-block elements called transition metals?

D-block elements are called transition metals because their atoms have incomplete d subshells or readily form ions with incomplete d subshells, exhibiting transition properties between s- and p-block elements. They show variable oxidation states, form complex ions, and display catalytic activity, crucial in many NEET and board exam questions.

6. Are d-block and f-block elements important for NEET 2025 Chemistry?

Yes, d- and f-block elements are highly important in the NEET 2025 Chemistry syllabus. Questions often test trends, electronic configurations, metallurgy, color, magnetic properties, and complex formation. Regular practice through chapter-wise mock tests can greatly improve performance in this section.

7. Can I download d and f-block elements mock test questions as PDF?

Yes. Most leading NEET preparation platforms, such as Vedantu, provide d and f-block elements mock test questions in PDF format. After taking the online test, you can download the question paper, answer keys, and detailed solutions for revision and offline practice.

8. What is included in a chapter-wise d and f block elements mock test for NEET?

A typical chapter-wise mock test covers all major NEET 2025 syllabus topics for d and f block elements, including electronic configuration, oxidation states, trends in properties, complexes, color, magnetic behavior, and applications. Detailed solutions and instant scoring help identify strengths and weaknesses.

9. What are the unique properties of f block elements?

F block elements exhibit variable oxidation states, high reactivity (especially actinides), lanthanide contraction, and generally form complexes. Most are paramagnetic and show poor shielding effect. Understanding these trends is essential for NEET Chemistry objective and assertion-reason questions.

10. What is the 'lanthanide contraction' and why is it important?

Lanthanide contraction refers to the steady decrease in the atomic and ionic radii of the lanthanide series elements from Cerium (Ce) to Lutetium (Lu). This is due to poor shielding of nuclear charge by 4f electrons. It affects the chemical properties of both lanthanides and following elements, explaining similarities in size and reactivity, which often appear in NEET and JEE questions.

11. Do d-block elements form colored compounds?

Yes, d-block elements typically form colored compounds due to electronic transitions between split d-orbitals in the presence of a ligand (crystal field splitting). This is a frequent topic in NEET and board exams for concept and direct MCQs.

12. Where can I take a free online NEET mock test for d and f block elements?

You can take free chapter-wise NEET mock tests for d and f block elements on trusted educational platforms like Vedantu, NTA Abhyas, and similar NEET practice sites. These tests are updated as per the NEET 2025 pattern and provide instant results, All India Rank prediction, and detailed solutions to boost your Chemistry preparation.
