NEET Chemistry Ionization Energy Assertion Reason Question
Assertion (A): The first ionization enthalpy is always less than the second ionization enthalpy for any element.
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 NCERT context explains that the second ionization enthalpy is always higher than the first because removing an electron from a positively charged ion is harder than from a neutral atom.
