Why is the first ionization enthalpy of noble gases higher than that of other elements?

Options

  1. ANoble gases have fewer electrons.
  2. BNoble gases have smaller nuclei.
  3. CNoble gases have more shielding electrons.
  4. DNoble gases have stable electron configurations.

Correct answer

D. Noble gases have stable electron configurations.

Step-by-step solution

Noble gases have closed electron shells and very stable electron configurations, leading to higher first ionization enthalpies.
