FAQs on D and F Block Elements JEE Main 2025-26: Mock Test for Top Scores
1. What are d-block elements?
d-block elements are chemical elements found in groups 3 to 12 of the periodic table. They are also called transition elements and have their last electron entering the (n-1)d orbital. Examples include iron (Fe), copper (Cu), and nickel (Ni).
2. What are f-block elements?
f-block elements are placed separately at the bottom of the periodic table and consist of the lanthanides and actinides. Their last electron enters the (n-2)f orbital. Common examples include uranium (U) and cerium (Ce).
3. Why are d-block elements called transition elements?
d-block elements are known as transition elements because their atoms have an incomplete d-subshell, or can give rise to cations with an incomplete d-subshell, leading to a transition in properties between s-block and p-block elements.
4. List examples of d-block elements.
Some representative examples of d-block elements are iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), chromium (Cr), and zinc (Zn).
5. What are the main properties of d-block elements?
Key properties of d-block elements include:
- Variable oxidation states
- Formation of coloured compounds
- Ability to form complex ions
- High melting and boiling points
- Good conductors of heat and electricity
6. What are the main properties of f-block elements?
Some important properties of f-block elements are:
- Known as inner transition elements
- Show variable oxidation states
- Form coloured ions
- Have high magnetic susceptibility
- Lanthanides are mainly trivalent, while actinides have more variable oxidation states
7. How can we remember the order of d-block elements easily?
You can use mnemonics and memory tricks to recall d-block sequences like: “Scary Titanium Vultures Crave Mango Fudge Coated Noisily, Easily, Creatively, Zinced” for Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn.
8. Why do transition elements form coloured compounds?
Most transition elements form coloured compounds due to the presence of partially filled d orbitals. Electronic transitions among different d-orbital energy levels absorb visible light and impart characteristic colours.
9. What is the difference between lanthanides and actinides?
Lanthanides (atomic numbers 57–71) are 4f-block elements and mostly show +3 oxidation state. Actinides (atomic numbers 89–103) are 5f-block elements and exhibit more variable oxidation states. Actinides are mostly radioactive while lanthanides are not.
10. Why are zinc, cadmium, and mercury not considered transition elements?
Though zinc (Zn), cadmium (Cd), and mercury (Hg) belong to the d-block, they are not true transition elements because they have completely filled d-subshells in both ground and common oxidation states, so they do not show characteristic transition properties.
11. What is the general electronic configuration of d-block and f-block elements?
d-block elements: General configuration is [noble gas] ns2 (n-1)d1-10.
f-block elements: General configuration is [noble gas] ns2 (n-2)f1-14 (n-1)d0-1.
12. Can you provide some important d and f-block questions for practice?
Yes! Here are some popular exam-style questions:
1. Write the electron configuration of Fe3+.
2. Why do transition metals show variable oxidation states?
3. Give two uses of lanthanides and actinides.
4. Why do f-block elements form coloured ions?
