Question

Match the following elements with their respective blocks in the periodic table:
 

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

Hint:

s-block: Group 1 and 2 elements (e.g., Alkali and Alkaline Earth Metals).
- p-block: Groups 13-18 elements.
- d-block: Transition metals.
- f-block: Lanthanides and Actinides.

Answer 1

The Correct Option is D

We classify the given elements based on their periodic table block: 1. Radium (Ra): - Belongs to Group 2 (Alkaline Earth Metals). - s-block → (A - II). 2. Ununquadium (Uuq) [Now known as Flerovium (Fl)]: - Group 14 element (same as Carbon family). - p-block → (B - I). 3. Darmstadtium (Ds): - Transition metal. - d-block → (C - IV). 4. Fermium (Fm): - Actinide series. - f-block → (D - III). Thus, the correct match is: \[ A - II, \quad B - I, \quad C - IV, \quad D - III \] Thus, the correct answer is \(\boxed{A - II, B - I, C - IV, D - III}\).
