Question
Among the elements $Li, Be, B,$ and $C$, which one possesses the highest second ionization enthalpy ($IE_2$)?
Answer: A
💡 Solution & Explanation
After losing one electron, $Li^+$ attains the highly stable $1s^2$ (Helium) noble gas configuration. Removing a second electron from this stable closed shell requires an immense amount of energy.
