Question:

$\text{Match Column I with Column II.}$\n\n$\text{Column-I}$\n$\text{(a) Copper}$\n$\text{(b) Fluorine}$\n$\text{(c) Silicon}$\n$\text{(d) Cerium}$\n\n$\text{Column-II}$\n$\text{(i) Non-metal}$\n$\text{(ii) Transition metal}$\n$\text{(iii) Lanthanoid}$\n$\text{(iv) Metalloid}$

Options:

1. $\text{(a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)}$
2. $\text{(a)-(ii), (b)-(i), (c)-(iv), (d)-(iii)}$ (Correct)
3. $\text{(a)-(iv), (b)-(iii), (c)-(i), (d)-(ii)}$
4. $\text{(a)-(i), (b)-(ii), (c)-(iii), (d)-(iv)}$

Solution:

$\text{HINT: Cerium is an f - block element.}$\n\n$\text{Explanation:}$\n\n$\text{The correct answer is as follows:}$\n\n$\text{1. Copper – Transition metal.}$\n\n$\text{2. Fluorine – Non-metal.}$\n\n$\text{3. Silicon – Metalloids.}$\n\n$\text{4. Cerium – Lanthanoid.}$
