Which halogen has the highest value of negative electron gain enthalpy?

Options

  1. AFluorine
  2. BChlorine
  3. CBromine
  4. DIodine

Correct answer

B. Chlorine

Step-by-step solution

The added electron goes to the bigger n = 3 is i.e., occupies larger region to space and the electron-electron repulsion is much less. So, Chlorine has the highest value of negative electron gain enthalpy
