NEET Chemistry Ionization Energy MCQ Question
Given that the first ionization enthalpy of element X is 500 kJ/mol, what could be a plausible value for its second ionization enthalpy?
750 kJ/mol
500 kJ/mol
1000 kJ/mol
300 kJ/mol
Correct Answer
Detailed Explanation
The second ionization enthalpy is higher than the first because it is more difficult to remove an electron from a positively charged ion than from a neutral atom.
