Question

Match the elements with the highest exhibited property:

	Column I		Column II
P	Cs	1	atomic size
Q	F	2	Electron affinity
R	Cl	3	Electronegativity
S	Ar	4	Metallic character

• A. $P-4,Q-3,R-2,S-1$
• B. $P-4,Q-3,R-1,S-2$
• C. $P-1,Q-2,R-3,S-4$
• D. $P-3,Q-2,R-4,S-1$

Answer 1

The correct option is A $P-4,Q-3,R-2,S-1$

$Cs$ has the highest metallic character.
Fluorine ($F$) is the most electronegative element
Chlorine ($Cl$) has the highest electron affinity
$Ar$ has van der Waals radius and hence it has greatest atomic radius.
