Question
According to the Mulliken scale, electronegativity is defined for an isolated gaseous atom. Which of the following pairs of thermodynamic processes strictly represents the energy changes required to evaluate the Mulliken electronegativity for an atom $X$?
Answer: A
💡 Solution & Explanation
Mulliken defined electronegativity as the arithmetic mean of the first ionization energy (IE) and the electron affinity (EA). IE corresponds to $X_{(g)} \rightarrow X^+_{(g)} + e^-$, and EA corresponds to the energy released in $X_{(g)} + e^- \rightarrow X^-_{(g)}$.
