JEE Main
JEE Main 2021
Classification of Elements and Periodicity in Properties
A
$S > Se > Te > O$
4%
B
$Te > Se > S > O$
36%
C
$O > S > Se > Te$
39%
D
$S > O > Se > Te$
21%
Solution:
correct order of electron gain enthalpy is :$O < S > Se > Te$
$\Rightarrow S > Se > Te > O$
(Oxygen shows least electron gain enthalpy due to small size of atom)
