NEET Chemistry Ionization Energy Assertion Reason Question
Assertion (A): The second ionization enthalpy of sodium is higher than its first ionization enthalpy.
Reason (R): It is more difficult to remove an electron from a positively charged ion than from a neutral atom.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true, but R is false.
A is false.
Correct Answer
Detailed Explanation
The second ionization enthalpy is always higher because energy is needed to remove an electron from a positively charged ion, as stated in the NCERT context.
