Chemistry QUESTION #7145

Question 5

The first ionization potential of Sodium ($Na$) is $5.1\text{ eV}$. What is the estimated value for the electron gain enthalpy of the $Na^{+}$ ion?

$2.55\text{ eV}$
$5.1\text{ eV}$✔️
$10.2\text{ eV}$
$+ 2.55\text{ eV}$

Correct Answer Logic:

The process of ionization for Sodium is: $Na \rightarrow Na^{+} + e^{-}$. The energy required for this is the ionization potential ($5.1\text{ eV}$). The reverse process is: $Na^{+} + e^{-} \rightarrow Na$. The energy released in this reverse process is the electron gain enthalpy of $Na^{+}$, which is equal in magnitude but opposite in sign to the ionization potential. Therefore, the value is $5.1\text{ eV}$.
