Question

Halogens have the highest electron gain enthalpies . Explain. ​

Answer 1

Answer:

PLEASE MARK ME AS BRAINLIEST

Explanation:

The halogens have a strong tendency to accept electrons due to their small size and effective nuclear charge so they have maximum negative electron gain enthalpy in their respective periods of the periodic table.

Answer 2

Answer:

The halogens have a strong tendency to accept electrons due to their small size and effective nuclear charge so they have maximum negative electron gain enthalpy in their respective periods of the periodic table.

Explanation:

Chlorine has the highest electron gain enthalpy. Although flourine is the most electronegative electron affinity of chlorine is higher as flourine due to its small size has a difficulty in accomodating an extra electron due to interelectronic repulsions.
