Question

How negative electron gain enthalpy varies in periodic table

Answer 1

║⊕ANSWER⊕║

• Electron gain enthalpy becomes more and more negative in a period from left to right.
• Halogens have the most negative electron gain enthalpy.
• As we move from chlorine to iodine, the electron gain enthalpies become less and less negative due to the corresponding increase in their atomic radii.
