Question

The correct match among the following is \[ \text{(a) Lithium, Sodium, Potassium} \qquad \text{(i) Alkaline earth metals} \] \[ \text{(b) Beryllium, Magnesium, Calcium} \qquad \text{(ii) Semi-metals} \] \[ \text{(c) Oxygen, Sulphur, Selenium} \qquad \text{(iii) Alkali metals} \] \[ \text{(d) Silicon, Germanium, Arsenic} \qquad \text{(iv) Chalcogens} \]

• A. (a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)
• B. (a)-(iv), (b)-(iii), (c)-(i), (d)-(ii)
• C. (a)-(iii), (b)-(i), (c)-(iv), (d)-(ii)
• D. (a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)
• E. (a)-(i), (b)-(ii), (c)-(iii), (d)-(iv)

Hint:

Group 1 elements are alkali metals, group 2 are alkaline earth metals, and group 16 are chalcogens.

Answer 1

The Correct Option is C

Match each group: - Lithium, Sodium, Potassium \(\to\) Alkali metals \((iii)\) - Beryllium, Magnesium, Calcium \(\to\) Alkaline earth metals \((i)\) - Oxygen, Sulphur, Selenium \(\to\) Chalcogens \((iv)\) - Silicon, Germanium, Arsenic \(\to\) Semi-metals \((ii)\) Thus: \[ (a)-(iii),\ (b)-(i),\ (c)-(iv),\ (d)-(ii) \] Hence, \[ \boxed{(C)} \]
