B) These energies are equal for all forms of the same element
Explanation:
The ionization energy for a chlorine atom is equal in magnitude to the electron affinity of Cl⁻ ion because these energies are equal for all forms of the same element.
Electron affinity is the energy released in adding an electron to a neutral atom in the gas phase.
Ionization energy is the amount of energy required for the removal of an electron in atom or ion.
Here the energy released when an electron is added to the Cl atom(electron affinity) to form a chlorine ion is the same energy that would be required to remove the added electron from the ion to form an atom(electronegativity).
Here we find out that both energies are the same for the atom of Cl that is gaining electron and for the ion in which electron is being removed.
