Question

Match the following

List I	List II
A. Technetium	I. Non-metal
B. Fluorine	II. Transition metal
C. Tellurium	III. Lanthanoid
D. Dysprosium	IV. Metalloid

• A. A-II, B-I, C-III, D-IV
• B. A-III, B-I, C-IV, D-II
• C. A-II, B-I, C-IV, D-III
• D. A-IV, B-I, C-II, D-III

Hint:

Classify each element: technetium is a d-block metal, fluorine a non-metal, tellurium a metalloid and dysprosium a 4f lanthanoid.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept
Elements are grouped as non-metals, metalloids, transition metals (d-block) or lanthanoids (4f series).

Step 2: Match each element
A. Technetium (Z = 43) is a d-block element, so a transition metal (II).
B. Fluorine is a halogen and a non-metal (I).
C. Tellurium lies between metals and non-metals, so it is a metalloid (IV).
D. Dysprosium (Z = 66) is a 4f element, a lanthanoid (III).

Step 3: Conclusion
The matching is A-II, B-I, C-IV, D-III.

Final Answer:
The correct matching is A-II, B-I, C-IV, D-III. \[ \boxed{\text{(C) }\text{A-II, B-I, C-IV, D-III}} \]
