Chapter 12, Problem 11DQ

Interpretation Introduction

Interpretation:Atom or ion that has equal magnitude of electron affinity as of ionization energy forchlorine atom should be determined.

Concept introduction:Ionization energy represents energy required for removal of outermost valence electron from gaseous atom. It can be represented by I .

  $\text{A}\to {\text{A}}^{+}+1e^{-}$

Electron affinity represents amount of energy releasedif1 electron is added to neutral atom.

  $\text{A}\left(g\right)+{\text{e}}^{-}\to {\text{A}}^{-}\left(g\right)$
