Match List I with List II

	LIST I (Elements)		LIST II (Properties in their respective groups)
A.	$\mathrm{Cl,S}$	I.	Elements with highest electronegativity
B.	$\mathrm{Ge,As}$	II.	Elements with largest atomic size
C.	$\mathrm{Fr,Ra}$	III.	Elements which show properties of both metals and non-metal
D.	$\mathrm{F,O}$	IV.	Elements with highest negative electron gain enthalpy

Choose the correct answer from the options given below:

<p>To match the elements from List I with their corresponding properties in List II, let's analyze each pair:</p> <p>A. $\mathrm{Cl,S}$<br> <p>These elements are known for having high negative electron gain enthalpy (energy released when an electron is added to an atom). Chlorine ($\mathrm{Cl}$) and sulfur ($\mathrm{S}$) are both elements that release a significant amount of energy when they gain an electron.<br></p> <p>Hence, they match with IV: Elements with highest negative electron gain enthalpy.</p></p> <p>B. $\mathrm{Ge,As}$<br> <p>Germanium ($\mathrm{Ge}$) and arsenic ($\mathrm{As}$) are metalloids, meaning they show properties of both metals and non-metals.<br></p> <p>Hence, they match with III: Elements which show properties of both metals and non-metal.</p></p> <p>C. $\mathrm{Fr,Ra}$<br> <p>Francium ($\mathrm{Fr}$) and radium ($\mathrm{Ra}$) are elements that have very large atomic sizes, being at the bottom of their respective groups on the periodic table.<br></p> <p>Hence, they match with II: Elements with largest atomic size.</p></p> <p>D. $\mathrm{F,O}$<br> <p>Fluorine ($\mathrm{F}$) and oxygen ($\mathrm{O}$) are elements with the highest electronegativity, meaning they strongly attract electrons toward themselves.<br></p> <p>Hence, they match with I: Elements with highest electronegativity.</p></p> <p>Summarizing, we have:</p> <p>A-IV, B-III, C-II, D-I</p> <p>The correct option is:</p> <p>Option D<br> <p>A-IV, B-III, C-II, D-I</p></p>
