Chemistry Question on Classification
Which one of the following elements has the highest negative value for its electron gain enthalpy?
A
Se
B
O
C
S
D
Te
Answer
S
Explanation
Solution
The elements of group 16 have relatively high negative electron gain enthalpy values which decrease down the group from S to Po. Oxygen has lowest negative electron gain enthalpy due to its small size which makes electron density high and repels the incoming electron
