Explain why the electron gain enthalpy of fluorine is less negative than that of chlorine?

Options

  1. AFluorine has a smaller atomic size, leading to stronger electron-electron repulsions.
  2. BChlorine has a higher nuclear charge, resulting in a stronger attraction for electrons.
  3. CFluorine has a completely filled inner electron shell, reducing its affinity for additional electrons.
  4. DChlorine's electron cloud is more diffuse, making it easier for the atom to accept an extra electron.

Correct answer

B. Chlorine has a higher nuclear charge, resulting in a stronger attraction for electrons.

Step-by-step solution

Correct Option is : (B) Chlorine has a higher nuclear charge, resulting in a stronger attraction for electrons.
