Halogens have maximum negative electron gain enthalpy in the respective periods of the periodic table. Why?
(N/A) Halogens have the smallest size in their respective periods and therefore high effective nuclear charge. As a consequence,they readily accept one electron to acquire noble gas electronic configuration.
